A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

Prevent plagiarism, run a free check.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

Structure of a Literature Review – Outline

When you write a literature review outline, you are laying the foundations of great work. Many people rush this part and struggle later on. Take your time and slowly draft the outline for a literature review.

The structure of a literature review consists of five main components:

• Introduction: Provide a brief overview of the chapter, along with the topic and research aims to set the context for the reader.
• Foundation of Theory or Theoretical Framework: Present and discuss the key theories, concepts, and models related to your research topic. Explain how they apply to your study and their significance.
• Empirical Research: Review and analyze relevant empirical related to your research question. Highlight their findings, methodologies, and any limitations they possess.
• Research Gap: Identify any gaps, inconsistencies, or ambiguities in the existing literature. This will help establish the need for your research and justify its relevance.
• Conclusion: Summarize the main findings from the literature review, emphasizing the importance of your research question and the identified research gap. Suggest potential avenues for future research in the field.

Sentence starters for each section of your literature review:

Literature review examples and types.

Based on the typology of literature reviews from Paré et al. (2015), the following list outlines various types of literature reviews and examples of when you’d use each type:

1. Conceptual Review: Analyzes and synthesizes the theoretical and conceptual aspects of a topic. It focuses on understanding key concepts, models, and theories.

Example use: When aiming to clarify the conceptual foundations and explore existing theories in a field, such as investigating the dimensions of job satisfaction.

2. Methodological Review: Evaluates and synthesizes the research approaches, methods, and techniques used in existing literature. It aims to identify methodological strengths and weaknesses in a research area.

Example use: When assessing data collection methods for researching user experiences with a new software application.

3. Descriptive Review: Provides a broad overview of studies in a research area. It aims to describe the existing literature on a topic and document its evolution over time.

Example use: When investigating the history of research on employee motivation and documenting its progress over the years.

4. Integrative Review: Combines and synthesizes findings from different studies to produce a comprehensive understanding of a research topic. It may identify trends, patterns, or common themes among various studies.

Example use: When exploring the links between work-life balance and job satisfaction, aggregating evidence from multiple studies to develop a comprehensive understanding.

5. Theory-driven Review: Examines a research topic through the lens of a specific theoretical framework. It focuses on understanding how the chosen theory explains or predicts phenomena in the literature.

Example use: When studying the impact of leadership styles on team performance, specifically using the transformational leadership theory as a basis for the analysis.

6. Evidence-driven Review: Aims to determine the effectiveness of interventions or practices based on the available research evidence. It can inform the decision-making process in practice or policy by providing evidence-based recommendations.

Example use: When assessing the effectiveness of telemedicine interventions for managing chronic disease outcomes, providing recommendations for healthcare providers and policymakers.

By understanding these types of literature reviews and their appropriate usage, researchers can choose the most suitable approach for their research question and contribute valuable insights to their field.

How to Write a Good Literature Review

To write a good literature review, follow these six steps to help you create relevant and actionable content for a young researcher.

1. Define the review’s purpose: Before starting, establish a clear understanding of your research question or hypothesis. This helps focus the review and prevents unnecessary information from being included.

2. Set inclusion and exclusion criteria: Use predefined criteria for including or excluding sources in your review. Establish these criteria based on aspects such as publication date, language, type of study, and subject relevance. This ensures your review remains focused and meets your objectives.

3. Search for relevant literature: Conduct a comprehensive search for literature relevant to your research question. Use databases, online catalogs, and search engines that focus on academic literature, such as Google Scholar, Scopus, or Web of Science. Consider using multiple search terms and synonyms to cover all related topics.

4. Organize and analyze information: Develop a system for organizing and analyzing the information you find. You can use spreadsheets, note-taking applications, or reference management tools like Mendeley, Zotero, or EndNote. Categorize your sources based on themes, author’s conclusions, methodology, or other relevant criteria.

5. Write a critique of the literature: Evaluate and synthesize the information from your sources. Discuss their strengths, weaknesses, and gaps in knowledge or understanding. Point out any inconsistencies in the findings and explain any varying theories or viewpoints. Provide a balanced critique that highlights the most significant contributions, trends, or patterns.

6. Structure the review: Organize your literature review into sections that present the main themes or findings. Start with an introduction that outlines your research question, the scope of the review, and any limitations you may have encountered. Write clear, concise, and coherent summaries of your literature for each section, and end with a conclusion that synthesizes the main findings, suggests areas for further research, and reinforces your research question or hypothesis.

Incorporating these steps will assist you in crafting a well-structured, focused, and informative literature review for your research project.

Here are some examples of each step in the process. 

Top Tips on How to Write Your Literature Review

Here are the top tips on how to write your literature review, based on the Grad Coach TV video and advice from trusted coach Amy:

1. Develop a rough outline or framework before you start writing your literature review. This helps you avoid creating a jumbled mess and allows you to organize your thoughts coherently and effectively.

2. Use previous literature reviews as a guide to understand the norms and expectations in your field. Look for recently published literature reviews in academic journals or online databases, such as Google Scholar, EBSCO, or ProQuest.

3. Write first and edit later. Avoid perfectionism and don’t be afraid to create messy drafts. This helps you overcome writer’s block and ensures progress in your work.

4. Insert citations as you write to avoid losing track of references. Make sure to follow the appropriate formatting style (e.g. APA or MLA) and use reference management tools like Mendeley to easily keep track of your sources.

5. Organize your literature review logically, whether it’s chronologically, thematically, or methodologically. Identify gaps in the literature and explain how your study addresses them. Keep in mind that the structure isn’t set in stone and can change as you read and write.

Remember that writing your literature review is an iterative process, so give yourself room to improve and make changes as needed. Keep these actionable tips in mind, and you’ll be well on your way to creating a compelling and well-organized literature review.

How To Write A Literature Review - A Complete Guide

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning to write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

Writing a literature review for a research paper is an important stage in the academic research process. It entails doing a critical review of existing literature to provide a comprehensive overview of current knowledge on a certain issue. In this article, we will walk you through the important processes for writing an excellent literature review. We’ll discuss how to discover relevant literature, combine findings, and arrange your review to provide clear insights. Whether you’re a seasoned researcher or a first-time writer, this guide will give you essential advice and tactics for improving the quality and impact of your literature reviews.

What Is a Literature Review?

A literature review is a survey of key scholarly sources to do with a particular topic. It lists a number of important and relevant pieces of writing and, in doing so, gives the reader a summary of the topic’s current knowledge and debates. When writing a literature review, a student should do more than just summarise each individual source. They should analyze them closely and compare them with one another.

A key part of academic writing involves understanding what has been said and debated about the chosen topic. Once a student has done their research, they’re in a better place to write their research paper and put their point across. A good literature review should let the reader know what the salient points from the student’s research are.

What Is the Purpose of a Literature Review?

The purpose of a literature review is to show the reader what research has been carried out on the chosen topic in the past. When writing one, you’re aiming to bring the reader up to speed with other people’s research before sharing your own findings. You should summarise where the topic’s at right now before building on it with your research.

Another important purpose is to give more weight to a student’s key arguments. By listing and comparing some of the key sources, a student can give context to the main points in their research paper; they can even fill any gaps in certain areas that others haven’t yet managed to fill.

If you want to know how to write a literature review in a research paper, carry on reading. We’ll run you through the process of putting one together, and we’ll talk about some of the different approaches you can take in writing one.

Steps in the Literature Review Process

A literature review can make a Ph.D. dissertation, or any other kind of  research paper more convincing. For a review to be effective, it should be detailed and have substance but without overdoing it; in other words, it should be concise.

If you’re not sure how to write a literature review for a research paper, we’ll show you how in this section. Here are the main steps to take:

• Decide on your topic Your topic is the base on which you build your research. It also determines what research you carry out.
• Search for sources to include The sources you look at for your research paper should be authoritative and relevant. They should be scholarly in nature, though not all of them will be.
• Determine which ones are the most useful Look through your sources and think about how much each one adds to both the topic you’re exploring and the research you’re carrying out. Including all sources isn’t practical, so only choose the most appropriate and fitting ones.
• Identify where the research is currently at By reading other people’s research, you can get an idea of what the current thoughts and debates relating to your chosen topic area.
• Come up with a structure Literature reviews have quite simple structures. More information on these is given below. Think about how you want to present yours and how you’re going to arrange your findings.
• Write your literature review A well-written literature review gives the reader all the necessary information about each of the sources. It clearly explains how the sources are connected and what they contribute to the chosen topic.

It’s a good idea to come up with headings and subheadings and go from there. These are both important, and we’ll talk about them in more detail later on. During the planning process, they can help you come up with a definitive structure for your literature review and consolidate your thoughts.

You may want to pay someone to write a literature review for you. Many people who are struggling with literature reviews do this. They don’t hand in the work that someone else has done for them. Instead, they read through the other person’s work to get ideas and inspiration. Doing this can help people write their own literature review much more effectively.

How to Structure a Literature Review

For this section, we’ll look at how to write a literature review. We’ll focus on the different approaches you can take according to the type of research you’re doing and how you wish to present it.

Chronological

Listing your sources in chronological order is perhaps the simplest approach to take. However, make sure you don’t just list the sources and summarise them. You should still try to establish some sort of connection between them. Highlight movements, patterns, and new ideas. Show the reader how scholarship on the topic has changed over time. You could even organize your sources into broad historical periods and have these as subheadings in the literature review, for example.

When writing a thematic literature review , you should organize your sources by theme. You should consider this approach if you’ve found multiple themes during your research. Create literature review subheadings for each theme that stands out to you. If you go for a thematic style, think about what your RRL subtopics are and what themes you would use to organize them.

Methodological

A methodological literature review is one whose sources involve the use of different research methods . You could have one source that’s numerical and involves graphs and statistics, for example, and another that’s entirely made up of written text. The subheadings in a literature review that’s methodological could focus on different types of research, focusing not so much on what has been researched but how it’s been researched. As a literature review subheadings example, you could therefore have one subheading for literary sources, another for numerical/graph-based data, and so on.

Theoretical

With a theoretical approach, the focus is on the body of theories relating to the topic that’s being discussed. The aim is to determine what theories there currently are, how they relate to one another, and how much they’ve been looked into.

These are just some of the different ways you can go about writing a literature review. The approach you take will depend on the nature of your review and the topic you’re looking at.

Writing a literature review can be an intimidating task to tackle, especially if you are not familiar with the literature in the field. Fortunately, there is a  paper writing service online that can help you create an outstanding literature review in no time. Our service is helpful for students, researchers, and others who need to compile a comprehensive and informative literature review.

Literature Review Outline

Writing a good outline for a literature review is important for your research paper. It helps you organize your thoughts and ideas and gives you a clear direction for the writing process.

An outline is not a formal document but rather an informal guide to assist you in organizing the information you want to include in your paper. The outline should be written in paragraph form, with each paragraph representing one major idea that will be expanded upon in subsequent paragraphs of the paper.

The main purpose of writing an outline is so that you can organize all of your sources in a way that will help you write a clear, concise essay. You just want to throw together quotes and facts without any order or reason. This will make it hard for the reader to follow along with what you are saying and make it appear that you have no idea what you’re talking about. This can result in a low grade for your paper and make it difficult for them to understand what is happening within the text.

• Introduction The introduction should include a brief summary of the literature that is being reviewed, including the general topic and your specific focus. You should also provide some background information on the topic to help the reader understand why it is important. You should not include any citations in this section, because you will do that later in the paper.
• Body The body is where you provide an overview of all the sources or literature, you have used for your paper. You should include an introduction to each source and a brief summary of what was found in each source. In addition to providing summaries, you should also describe how each source relates to your research question or hypothesis and then relate them back to each other if they are similar enough to be compared. Finally, you should explain how each source relates to one another in addition to explaining how they relate to your research question or hypothesis.
• Conclusion The conclusion should summarize your arguments throughout the paper and then tie all of these things together into one coherent argument that proves or disproves your hypothesis or research question in relation to other sources discussed throughout this paper (and/or).

Writing a literature review is an integral part of a successful research article or dissertation, as it helps to synthesize and connect the existing body of knowledge. To write your lit review relevantly, it is important to ensure that you include new information when constructing your review and connect existing ideas and themes. A useful literature review outline can provide a structure for expressing your views, allowing you to connect and organize your ideas consistently and effectively.

Literature Review: Writing Tips

When writing a literature review, it’s important to include all of the information your assignment requires. Sometimes, instructors will give you specific guidelines for how long your literature review should be and how many sources it needs to include. If they don’t, however, you’ll need to decide what works best for your situation.

A literature review outline will be the foundation of your paper. It will tell you what information is important and how to write it cohesively and logically. When writing, it’s important to only include facts backed up by evidence. This means that if you are writing about any research topic, there must be at least one piece of published work that backs up each claim or opinion you present.

If there isn’t a source supporting your writing, don’t put it in because it makes your paper seem like speculation or opinion rather than fact-based knowledge about the issue at hand. Another tip for writers is to write clearly and concisely so that readers can understand what they are reading quickly without having any difficulty following along from one point to another throughout the entire essay (or book).

Readers may get bored very quickly if they feel like they have to struggle through something too much before getting into where things go next. Therefore, proper grammar usage should also be kept while doing this type as well, so there are no mistakes left behind after editing later down the line during the publishing stage itself.

The following are the most important tips for writing a literature review:

• Make sure that each paragraph covers a single subject or idea.
• Start with a thesis statement, which should sum up the paper’s main idea in one sentence.
• Write each paragraph in a way that flows from one point to another logically and coherently.
• Include quotes and paraphrases from sources you have read in order to support your arguments and conclusions.
• Make sure that you use credible sources as evidence for your claims and arguments in your paper.

As well as learning how to write a literature review for a research paper, you’ll learn to be more productive and use your time more wisely. Writing services help you put together literature reviews more efficiently. They give you the opportunity to work with an experienced writer who can offer tips in writing RRL, help you with literature review formatting, and more. For example, you can even get things like literature review headings and subheadings so you can see how best to write your headings.

Remember that while the literature review isn’t the main part of a research assignment, it’s still significant. It’s important that you write it as best you can so that your research has more backing and will be taken more seriously.

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

• Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 
• Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field. 
• Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 
• Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 
• Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 
• Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning. 

How to write a good literature review

Writing a literature review involves summarizing and synthesizing existing research on a particular topic. A good literature review format should include the following elements. 

Introduction: The introduction sets the stage for your literature review, providing context and introducing the main focus of your review. 

• Opening Statement: Begin with a general statement about the broader topic and its significance in the field. 
• Scope and Purpose: Clearly define the scope of your literature review. Explain the specific research question or objective you aim to address. 
• Organizational Framework: Briefly outline the structure of your literature review, indicating how you will categorize and discuss the existing research. 
• Significance of the Study: Highlight why your literature review is important and how it contributes to the understanding of the chosen topic. 
• Thesis Statement: Conclude the introduction with a concise thesis statement that outlines the main argument or perspective you will develop in the body of the literature review. 

Body: The body of the literature review is where you provide a comprehensive analysis of existing literature, grouping studies based on themes, methodologies, or other relevant criteria. 

• Organize by Theme or Concept: Group studies that share common themes, concepts, or methodologies. Discuss each theme or concept in detail, summarizing key findings and identifying gaps or areas of disagreement. 
• Critical Analysis: Evaluate the strengths and weaknesses of each study. Discuss the methodologies used, the quality of evidence, and the overall contribution of each work to the understanding of the topic. 
• Synthesis of Findings: Synthesize the information from different studies to highlight trends, patterns, or areas of consensus in the literature. 
• Identification of Gaps: Discuss any gaps or limitations in the existing research and explain how your review contributes to filling these gaps. 
• Transition between Sections: Provide smooth transitions between different themes or concepts to maintain the flow of your literature review. 

Conclusion: The conclusion of your literature review should summarize the main findings, highlight the contributions of the review, and suggest avenues for future research. 

• Summary of Key Findings: Recap the main findings from the literature and restate how they contribute to your research question or objective. 
• Contributions to the Field: Discuss the overall contribution of your literature review to the existing knowledge in the field. 
• Implications and Applications: Explore the practical implications of the findings and suggest how they might impact future research or practice. 
• Recommendations for Future Research: Identify areas that require further investigation and propose potential directions for future research in the field. 
• Final Thoughts: Conclude with a final reflection on the importance of your literature review and its relevance to the broader academic community. 

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research. 

The literature review sample and detailed advice on writing and conducting a review will help you produce a well-structured report. But remember that a literature review is an ongoing process, and it may be necessary to revisit and update it as your research progresses. 

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

The structure of a literature review

A literature review should be structured like any other essay: it should have an introduction, a middle or main body, and a conclusion.

Introduction

The introduction should:

• define your topic and provide an appropriate context for reviewing the literature;
• establish your reasons – i.e. point of view – for
• reviewing the literature;
• explain the organisation – i.e. sequence – of the review;
• state the scope of the review – i.e. what is included and what isn’t included. For example, if you were reviewing the literature on obesity in children you might say something like: There are a large number of studies of obesity trends in the general population. However, since the focus of this research is on obesity in children, these will not be reviewed in detail and will only be referred to as appropriate.

The middle or main body should:

• organise the literature according to common themes;
• provide insight into the relation between your chosen topic and the wider subject area e.g. between obesity in children and obesity in general;
• move from a general, wider view of the literature being reviewed to the specific focus of your research.

The conclusion should:

• summarise the important aspects of the existing body of literature;
• evaluate the current state of the literature reviewed;
• identify significant flaws or gaps in existing knowledge;
• outline areas for future study;
• link your research to existing knowledge.

🔭 literature review outline: general information.

Literature reviews are written mostly in sciences and social sciences, and sometimes in humanities. A literature review aims to discuss published information on the studies in a particular area. The most simple version of a literature review can be a mere summary of the sources. However, it usually features an organizational pattern and implies not only summary but also synthesis.

A literature review aims to provide a reader with a clear and understandable guide to a particular research topic. And for its writer, a solid review is an excellent opportunity to show them as an expert in a chosen field.

As MLA, Chicago, or APA style cover page generators help students with the very first part of any paper, the key to a successful literature review is a good outline . When planning a literature review, remember that no matter whether you’re dealing with a Chicago, MLA, or APA literature review outline, you’ll have to remember several important things.

📑 Literature Review Outline: Approaches to Structuring

A well-formed vision of the writing strategy before you start the main body paragraphs is half of the success. There are four approaches to arranging a literature review. Depending on the intended length of your paper, you can combine some or all of them. For instance, more than often, thematic and methodological strategies comprise a theoretical approach when it comes to details.

Just in 1 hour! We will write you a plagiarism-free paper in hardly more than 1 hour

Chronological Approach

Tracing the reviewed works in succession, starting with the earliest available materials, is the easiest way to examine the specific topic. Be careful not to list the works in chronological order with their summaries. The purpose of such a review is to find out the key patterns, central debates, and turning points of the prevailing opinion at specific periods.

Here is a sample to make the approach clear. If the first available source dates 1995, and the most recent one was written in 2017, divide your analysis into decades: 1995 – 2000, 2001 – 2010, and 2010 – present.

The chronological approach can perfectly combine with thematic or methodological ones. In such a case, the timescale is divided not by decades but by periods characterized by a predominant methodology or preferred theme.

Thematic Approach

This method is organized around a particular issue, rather than time progression. If you have found recurring themes in the course of your reading, it is an excellent idea to focus the review on them. As a rule, the thematic approach requires an in-depth study of the available scientific literature. It also looks more substantial and time-consuming than the chronological one.

Here, the sections dwell upon different issues or various aspects of one topic. For example, an overview of psychology literature on nonverbal communication can be divided into the following parts: facial expressions, postures, eye contact, gestures, touch, etc.

Methodological Approach

Sometimes the results of findings are not as outstanding as the ways of obtaining those results. A review of research methods provides a profound scientific understanding of the subject field, notably the approaches to data collection, study, and systematization. It also provides an insight into how scientists went from isolated data to a concept, and from the concept to practical conclusions.

This form proves to be the most successful in the analysis of multidisciplinary works. You can list all the methods used and conclude on their efficiency. Alternatively, you can compare the qualitative and quantitative, empirical and theoretical, or any other incompatible methodology. The materials for analysis are the results obtained by such or another method.

Theoretical Approach

Very often, a literature review becomes the basis for a theoretical framework of a research paper. In this case, the theoretical approach is the most effective way to structure the report.

Wherever you can single out several theories on a single phenomenon, different models of a system, or diverging definitions of the same concept, the theoretical approach is the best choice. The purpose is to analyze the corpus of theory that has accumulated regarding an idea, opinion, or event. Usually, this form establishes the existing scientific knowledge gaps and finds out the outstanding research questions.

✍️ Literature Review Outline: Writing Tips

When you start writing a literature review, you should keep the following issues in mind:

• Use evidence to support your interpretation of available sources.
• Be selective. Limit your literature review to sources relevant to the topic of your research. You should select only the most important points in each source.
• Compare and contrast the views of different authors. Organize the material for your reader to show trends in the literature.
• Use quotes sparingly. Apply them only when you want to emphasize the author’s point and cannot rewrite it in your own words. Always focus on giving your own summary and interpretation of the literature, showing your original thinking and analysis.
• Paraphrase in your own words to explain authors’ ideas . Give references to other sources when you are writing, but start and end the paragraphs with your own ideas.
• Summarize and synthesize your literature review sources. Identify the main points in a concise manner for your readers. Evaluate your sources , consider their strengths and weaknesses, compare and contrast the results of the studies, and discuss the strength of the evidence.
• Look for gaps in the existing research. Think about what aspects of your literature review topic have not yet been explored.
• Be creative!
• Draft and redraft. Improve the quality of your literature review by editing and proofreading.

✏️ Literature Review FAQ

The way such paper should look like is best presented in the form of an outline . A simplified form would include an introduction, 3+ paragraphs (preferably with 2+ subparagraphs in each) as a review body, and a conclusion.

You should write about your interpretation of the literary piece. Include your understanding of the author’s message and the way he puts that idea across (scenes, characters, allusions, etc.). For a research paper, however, include more precise details than personal impressions.

Outlines for a paper should list concise notes about the structure of the text and its content (usually in the format of bullet points). Remember that an outline is not a research proposal or dissertation, so do not write about the goals, objectives, methods, etc.

Do you have a list of ideas you want to describe in the paper already? If so, just make those notes structured in logical consequence and format them as bullet points highlighting the gist of each part.

Hello! Our experts will help you with any task!

HI, how long would you suggest an undergraduate’s final year research paper should be? ( minimum in pages for both quanti and quali researches) and is 15 pages of literature review( double spacing okay?

It would probably be between 10 and 20 pages. But it all comes down to the specific topic and instructions given. Fifteen pages for a literature review sounds good, if it’s an independent type of assignment. However, if it’s part of the undergraduate’s final year research paper mentioned above, then fifteen pages is probably too much. But, again, it all depends on the instructions, topic, etc.

thankyouuuu!!!!!!! best one so far

We are glad to hear your opinion! Thank you, Sadia🙂!

useful blog keep going

Thank you, Soran! Glad you found the blog useful 🙂

Thank you so much. This was so helpful, especially with your examples of an outline.

I’m glad the article was helpful for you, Jane!

I am working on a literary review on a couple of articles having to do with college football players getting paid. I have started my intro with info about the college athletic industry and how it is controversial, but how do I introduce/transition into the articles and the actually literary review?

Try to go with the facts, and stick with them. It would work kind of well, Janeth.

Thanks for stopping by. Try to write about features, positive and negative ones.

How to Write a Literature Review

As every student knows, writing informative essay and research papers is an integral part of the educational program. You create a thesis, support it using valid sources, and formulate systematic ideas surrounding it. However, not all students know that they will also have to face another type of paper known as a Literature Review in college. Let's take a closer look at this with our custom essay writer .

Literature Review Definition

As this is a less common academic writing type, students often ask: "What is a literature review?" According to the definition, a literature review is a body of work that explores various publications within a specific subject area and sometimes within a set timeframe.

This type of writing requires you to read and analyze various sources that relate to the main subject and present each unique comprehension of the publications. Lastly, a literature review should combine a summary with a synthesis of the documents used. A summary is a brief overview of the important information in the publication; a synthesis is a re-organization of the information that gives the writing a new and unique meaning.

Typically, a literature review is a part of a larger paper, such as a thesis or dissertation. However, you may also be given it as a stand-alone assignment.

The Purpose

The main purpose of a literature review is to summarize and synthesize the ideas created by previous authors without implementing personal opinions or other additional information.

However, a literature review objective is not just to list summaries of sources; rather, it is to notice a central trend or principle in all of the publications. Just like a research paper has a thesis that guides it on rails, a literature review has the main organizing principle (MOP). The goal of this type of academic writing is to identify the MOP and show how it exists in all of your supporting documents.

Why is a literature review important? The value of such work is explained by the following goals it pursues:

• Highlights the significance of the main topic within a specific subject area.
• Demonstrates and explains the background of research for a particular subject matter.
• Helps to find out the key themes, principles, concepts, and researchers that exist within a topic.
• Helps to reveal relationships between existing ideas/studies on a topic.
• Reveals the main points of controversy and gaps within a topic.
• Suggests questions to drive primary research based on previous studies.

Here are some example topics for writing literature reviews:

• Exploring racism in "To Kill a Mockingbird," "The Adventures of Huckleberry Finn," and "Uncle Tom's Cabin."
• Isolationism in "The Catcher in the Rye," "Frankenstein," and "1984"
• Understanding Moral Dilemmas in "Crime and Punishment," "The Scarlet Letter," and "The Lifeboat"
• Corruption of Power in "Macbeth," "All the King's Men," and "Animal Farm"
• Emotional and Physical survival in "Lord of the Flies," "Hatchet," and "Congo."

How Long Is a Literature Review?

When facing the need to write a literature review, students tend to wonder, "how long should a literature review be?" In some cases, the length of your paper's body may be determined by your instructor. Be sure to read the guidelines carefully to learn what is expected from you.

Keeping your literature review around 15-30% of your entire paper is recommended if you haven't been provided with specific guidelines. To give you a rough idea, that is about 2-3 pages for a 15-page paper. In case you are writing a literature review as a stand-alone assignment, its length should be specified in the instructions provided.

Literature Review Format: APA, MLA, and Chicago

The essay format you use should adhere to the citation style preferred by your instructor. Seek clarification from your instructor for several other components as well to establish a desired literature review format:

• How many sources should you review, and what kind of sources should they be (published materials, journal articles, or websites)?
• What format should you use to cite the sources?
• How long should the review be?
• Should your review consist of a summary, synthesis, or a personal critique?
• Should your review include subheadings or background information for your sources?

If you want to format your paper in APA style, then follow these rules:

• Use 1-inch page margins.
• Unless provided with other instructions, use double-spacing throughout the whole text.
• Make sure you choose a readable font. The preferred font for APA papers is Times New Roman set to 12-point size.
• Include a header at the top of every page (in capital letters). The page header must be a shortened version of your essay title and limited to 50 characters, including spacing and punctuation.
• Put page numbers in the upper right corner of every page.
• When shaping your literature review outline in APA, don't forget to include a title page. This page should include the paper's name, the author's name, and the institutional affiliation. Your title must be typed with upper and lowercase letters and centered in the upper part of the page; use no more than 12 words, and avoid using abbreviations and useless words.

For MLA style text, apply the following guidelines:

• Double your spacing across the entire paper.
• Set ½-inch indents for each new paragraph.
• The preferred font for MLA papers is Times New Roman set to 12-point size.
• Include a header at the top of your paper's first page or on the title page (note that MLA style does not require you to have a title page, but you are allowed to decide to include one). A header in this format should include your full name; the name of your instructor; the name of the class, course, or section number; and the due date of the assignment.
• Include a running head in the top right corner of each page in your paper. Place it one inch from the page's right margin and half an inch from the top margin. Only include your last name and the page number separated by a space in the running head. Do not put the abbreviation p. before page numbers.

Finally, if you are required to write a literature review in Chicago style, here are the key rules to follow:

• Set page margins to no less than 1 inch.
• Use double spacing across the entire text, except when it comes to table titles, figure captions, notes, blockquotes, and entries within the bibliography or References.
• Do not put spaces between paragraphs.
• Make sure you choose a clear and easily-readable font. The preferred fonts for Chicago papers are Times New Roman and Courier, set to no less than 10-point size, but preferably to 12-point size.
• A cover (title) page should include your full name, class information, and the date. Center the cover page and place it one-third below the top of the page.
• Place page numbers in the upper right corner of each page, including the cover page.

Structure of a Literature Review

How to structure a literature review: Like many other types of academic writing, a literature review follows a typical intro-body-conclusion style with 5 paragraphs overall. Now, let’s look at each component of the basic literature review structure in detail:

• Introduction

You should direct your reader(s) towards the MOP (main organizing principle). This means that your information must start from a broad perspective and gradually narrow down until it reaches your focal point.

Start by presenting your general concept (Corruption, for example). After the initial presentation, narrow your introduction's focus towards the MOP by mentioning the criteria you used to select the literature sources you have chosen (Macbeth, All the King's Men, and Animal Farm). Finally, the introduction will end with the presentation of your MOP that should directly link it to all three literature sources.

Body Paragraphs

Generally, each body paragraph will focus on a specific source of literature laid out in the essay's introduction. As each source has its own frame of reference for the MOP, it is crucial to structure the review in the most logically consistent way possible. This means the writing should be structured chronologically, thematically or methodologically.

Chronologically

Breaking down your sources based on their publication date is a solid way to keep a correct historical timeline. If applied properly, it can present the development of a certain concept over time and provide examples in the form of literature. However, sometimes there are better alternatives we can use to structure the body.

Thematically

Instead of taking the "timeline approach," another option can be looking at the link between your MOP and your sources. Sometimes, the main idea will just glare from a piece of literature. Other times, the author may have to seek examples to prove their point. An experienced writer will usually present their sources by order of strength. For example, in "To Kill A Mockingbird," the entire novel was centralized around racism; in "The Adventures of Huckleberry Finn," racism was one of many themes.

Methodologically

As made obvious by the terminology, this type of structuring focuses on the methods used to present the central concept. For example, in "1984", George Orwell uses the law-and-order approach and shows the dangers of a dystopia for a social species.

In "Frankenstein," Mary Shelley exposes the character's physical traits as repulsive and horrifying, forcing him to suffer in an isolated environment. By showcasing the various methods used to portray the MOP, the writer can compare them based on things like severity, ethicality, and overall impact.

After presenting your key findings in the body paragraphs, there are 3 final objectives to complete in the essay's conclusion. First, the author should summarize the findings they have made or found, in other words, and briefly answer the question: "What have you learned?"

After discussing that information, the next step is to present the significance of the information about our current world today. In other words, how can the reader take the information and apply it to today's society? From that point, we finish off with a breadcrumb trail.

As the author, you want to leave the readers' trail of thought within the actual essay topic. This provides them with a means of further investigation—meaning that the reader may consider where the discussion will go next.

Writing an Outline for a Literature Review

Students often underestimate the importance of planning the structure of their papers in advance. However, this is not a wise approach. Having a rough APA literature review outline (or other style outlines) will not only help you follow the right format and structure but will also make the writing process simpler and help ensure that you include all of the important information without missing anything.

How to write a literature review outline: As you already know from the Structure section of this guide, every part of your literature review performs its own important role. Therefore, you should create your outline while keeping the general introduction-body-conclusion structure in mind and ensuring that each section meets its own objectives. However, it is important to remember that a literature review outline is slightly different from outlines of other types of essays because it does not provide new information. Instead, it focuses on existing studies relevant to the main topic. ‍

Here is a literature review outline example on the subject of the Ebola virus to help you get it right:

• Introduce the general topic. Provide background information on the Ebola virus: genome, pathogenesis, transmission, epidemiology, treatment, etc.
• Shape the main research question: What is the potential role of arthropods (mechanical or biological vectors) in the distribution of the Ebola virus?
• Methodology: For example, the information was searched through X databases to find relevant research articles about the Ebola virus and arthropods' role in its spreading. The data was extracted using a standardized form.
• Expected outcomes
• Overall trends in the literature on this topic: While the natural reservoir of the virus is still not known with certainty, many researchers believe that arthropods (and fruit bats, in particular) pay a significant role in the distribution of the virus.
• Subject 1: A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Subject 2: A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Subject 3:  A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Indicate the relationships between the pieces of literature discussed. Emphasize key themes, common patterns, and trends. Talk about the pros and cons of the different approaches taken by the authors/researchers.
• State which studies seem to be the most influential.
• Emphasize the major contradictions and points of disagreement. Define the gaps still to be covered (if any).
• If applicable: define how your own study will contribute to further disclosure of the topic.

Hopefully, this sample outline will help you to structure your own paper. However, if you feel like you need some more advice on how to organize your review, don’t hesitate to search for more literature review outline examples in APA or other styles on the Web, or simply ask our writers to get a dissertation help .

How to Write a Good Literature Review

Whether you are writing a literature review within the framework of a large research project (e.g. thesis, dissertation, or other) or as a stand-alone assignment, the approach you should take to writing generally remains the same.

Whether you are writing a literature review within the framework of a large research project (e.g., thesis, dissertation, or other) or as a stand-alone assignment, the approach you should take to writing generally remains the same.

Now, as you know about the general rules and have a basic literature review outline template, let's define the steps to take to handle this task right with our service:

Step 1: Identifying the Topic

This is probably the only matter you may approach differently depending on whether your literature review comes within a research paper or a separate assignment altogether. If you are creating a literature review as a part of another work, you need to search for literature related to your main research questions and problems. Respectively, if you are writing it as a stand-alone task, you will have to pick a relevant topic and central question upon which you will collect the literature. Earlier in this guide, we suggested some engaging topics to guide your search.

Step 2: Conducting Research

When you have a clearly defined topic, it is time to start collecting literature for your review. We recommend starting by compiling a list of relevant keywords related to your central question—to make the entire research process much simpler and help you find relevant publications faster.

When you have a list of keywords, use them to search for valid and relevant sources. At this point, be sure to use only trusted sources, such as ones from university libraries, online scientific databases, etc.

Once you have found some sources, be sure to define whether or not they are actually relevant to your topic and research question. To save time, you can read abstracts to get general ideas of what the papers are about instead of the whole thing.

Pro Tip: When you finally find a few valid publications, take a look at their bibliographies to discover other relevant sources as well.

Step 3: Assess and Prioritize Sources

Throughout your research, you will likely find plenty of relevant literature to include in your literature review. At this point, students often make the mistake of trying to fit all the collected sources into their reviews. Instead, we suggest looking at what you've collected once more, evaluating the available sources, and selecting the most relevant ones. You most likely won't be able to read everything you find on a given topic and then be able to synthesize all of the sources into a single literature review. That's why prioritizing them is important.

To evaluate which sources are worth including in your review, keep in mind the following criteria:

• Credibility;
• Innovation;
• Key insights;

Furthermore, as you read the sources, don’t forget to take notes on everything you can incorporate into the review later. And be sure to get your citations in place early on. If you cite the selected sources at the initial stage, you will find it easier to create your annotated bibliography later on.

Step 4: Identify Relationships, Key Ideas, and Gaps

Before you can move on to outlining and writing your literature review, the final step is determining the relationships between the studies that already exist. Identifying the relationships will help you organize the existing knowledge, build a solid literature outline, and (if necessary) indicate your own research contribution to a specific field.

Some of the key points to keep an eye out for are:

• Main themes;
• Contradictions and debates;
• Influential studies or theories;
• Trends and patterns;

Here are a few examples: Common trends may include a focus on specific groups of people across different studies. Most researchers may have increased interest in certain aspects of the topic regarding key themes. Contradictions may include some disagreement concerning the theories and outcomes of a study. And finally, gaps most often refer to a lack of research on certain aspects of a topic.

Step 5: Make an Outline

Although students tend to neglect this stage, outlining is one of the most important steps in writing every academic paper. This is the easiest way to organize the body of your text and ensure that you haven't missed anything important. Besides, having a rough idea of what you will write about in the paper will help you get it right faster and more easily. Earlier in this guide, we already discussed the basic structure of a literature review and gave you an example of a good outline. At this workflow stage, you can use all of the knowledge you've gained from us to build your own outline.

Step 6: Move on to Writing

Having found and created all of your sources, notes, citations, and a detailed outline, you can finally get to the writing part of the process. At this stage, all you need to do is follow the plan you've created and keep in mind the overall structure and format defined in your professor's instructions.

Step 7: Adding the Final Touches

Most students make a common mistake and skip the final stage of the process, which includes proofreading and editing. We recommend taking enough time for these steps to ensure that your work will be worth the highest score. Do not underestimate the importance of proofreading and editing, and allocate enough time for these steps.

Pro Tip: Before moving on to proofreading and editing, be sure to set your literature review aside for a day or two. This will give you a chance to take your mind off it and then get back to proofreading with a fresh perspective. This tip will ensure that you won't miss out on any gaps or errors that might be present in your text.

These steps will help you create a top-notch literature review with ease! Want to get more advice on how to handle this body of work? Here are the top 3 tips you need to keep in mind when writing a literature review:

1. Good Sources

When working on a literature review, the most important thing any writer should remember is to find the best possible sources for their MOP. This means that you should select and filter through about 5-10 different options while doing initial research.

The stronger a piece of literature showcases the central point, the better the quality of the entire review.

2. Synthesize The Literature

Make sure to structure the review in the most effective way possible, whether it be chronologically, thematically, or methodologically. Understand what exactly you would like to say, and structure the source comparison accordingly.

3. Avoid Generalizations

Remember that each piece of literature will approach the MOP from a different angle. As the author, make sure to present the contrasts in approaches clearly and don't include general statements that offer no value.

Literature Review Examples

You can find two well-written literature reviews by the EssayPro writing team below. They will help you understand what the final product of a literature review should ideally look like.

The first literature review compares monolingual and bilingual language acquisition skills and uses various sources to prove its point:

What Is a Literature Review Outline?

A literature review outline is a sketch highlighting how you will convey information about your findings after evaluating and interpreting studies. In other words, it offers a rough overview of the sources you have analyzed in the paper.  Think of a literature outline as a general skeleton of what your full review should look like including the specifics of each part. Its purpose is to assist you in developing ideas, performing research and presenting your findings logically. Specifically, a literary review outline helps you sum up the arguments that you want to emphasize or what you will talk about in your study.

Elements of Literature Review Outline

Now that you know what a literature review outline means, you need to understand the major parts that must be incorporated. In general, it is organized in a similar way to a standard academic essay outline template with three key elements including an introduction, body, and conclusion. You may include subheadings within each part to divide them up into meaningful segments. An outline of a literature review has:

• Introduction Hooks the reader and offers an overview of your topic.
• Body Comprises headings, subheadings, and paragraphs for mapping out your argument.
• Conclusion Summarizes your key points.

Introduction  To create an effective introduction for a literature review, attract readers with a hook . This can be a quotation, example, or question. Introduce the research topic by briefly mentioning key concepts and describing your perspective. Discuss the literature you will review and provide hints about your fundamental concept. Overall, the introduction should bring interest to your research topic and provide readers with an understanding of what to expect in the text. In addition to outlining the key components of your literature review, it's important to address any debates or concerns related to your topic. This provides context and helps readers understand the significance of your exploration. Be sure to mention the importance of your research in your literature review outline and articulate your problem statement or research question .  Keep in mind that references should be included in the subsequent sections of your review.

Body The body of your review is where you analyze and interpret results to support your argument. This section should be well-organized and provide a clear and thorough analysis of the gathered studies.  Structure the information consistently and synthesize the main points while also evaluating the strengths and weaknesses of your sources.  You can use one of the approaches described in the next section to structure your information in body paragraphs . Ensure your work flows systematically and is easier to understand by using transitions words , headings, and subheadings. In your literature review outline, introduce each article you have used for the project and provide a brief description. Briefly explain the relationship between the texts and your dissertation topic , and highlight how the papers are interrelated.

The conclusion is where you present your final evaluation. Begin by identifying the main themes you have discovered and their line of research. Then, mention any strengths and weaknesses you have found in the literature and highlight your work’s significance to existing knowledge. In general, the conclusion of your outline for a literature review should briefly:

• Identify major agreements and disagreements in the studies reviewed.
• Provide an in-depth explanation of your findings.
• Describe any gaps or areas that require further research.
• Offer recommendations for future study.
• Provide your overall perspective on the issue.
• Clarify the importance of the topic within the current academic discourse.

Once you build an outline, your next step is to create a literature review itself. Check out our helpful blog with step-by-step guidance on how to write a literature review . 

Literary Review Outline: Main Approaches

Before composing the outline of a literary review, you should think about the various ways of arranging your points. Generally, there are 4 major options for organizing information when writing a literature review outline. The format you choose depends on your specific inquiry, aims, and other requirements. These approaches include:

• Theoretical
• Chronological
• Methodological.

Putting together your work well simplifies the entire process. Also remember to follow one structure consistently to avoid confusions with your flow. For example, if you decide to organize your work chronologically, make sure that you use this layout across your paper.

Theoretical Approach

A theoretical approach to literature review involves examining existing literature through a specific theoretical framework . Here, you need to view the literature through the lens of a particular theory or theories to gain a deeper understanding of your research question.  Theoretical approach can help identify patterns and inconsistencies not apparent through other methods. It’s especially useful if you are dealing with multiple theories or perspectives.  Divide your discussion into headings or subheadings following a particular order as shown below in the example:

• Brief description.
• Brief description, etc.

This is accompanied with brief discussions of each framework and their relevance to your paper. Look at this diagram for better understanding:

Chronological Approach

Chronological approach (linear approach) is the simplest way of structuring your body section. Start with older studies and work towards more recent ones. This streamlines the analysis of debates about your topic over time as you write your literature review outline. Additionally, the linear organization enables you to identify those texts that have had a profound impact on your field. Arrange your sources in a chronological order to understand how your theme has changed over time. Using this approach, you focus on important turning points rather than all events.  Here is a pictorial illustration of this model.

Thematic Approach

Thematic approach to an outline for a literature review involves grouping your works by themes. Here, researchers determine specific patterns or subjects to arrange sources thematically.  Use the themes you have identified as headings or subheadings in your body paragraphs.Then, summarize the relevant information under each theme to keep your discussion organized and easy-to-follow. This allows you to place all sources focusing on a similar topic together which makes it easier to ascertain where differences in opinions or perspectives arise. It is a commonly used structure across diverse fields. Consider the following diagram for further explanation.

Methodological Approach

With the methodological approach, your literature review outline is organized based on specific research methodologies applied in the studies. This model is useful when you need to investigate research questions related to particular methods, such as qualitative or quantitative study .  This approach allows researchers to recognize the strengths and weaknesses of various methods, and identify any gaps or areas where further investigation is needed. You will later use your revelations when designing a research study and writing a methodology .  Have a look at the diagram below to organize your review methodologically:

Literature Review Outline Template

If creating an outline is still challenging for you at this point, don’t worry because you can use a ready-made literature review outline template. Most institutions usually provide completed models. This makes your work easier because you will just fill in the details for each section.  The format can be APA, MLA, Chicago, or Harvard, which is generally specified in the task instructions. Thus, you should not face any difficulties finding a particular layout that may be applied to literature review when writing a dissertation .  Still, you can use the following outline for literature review template example and include relevant information according to your work.

• Identify your topic and its importance in the field
• Describe your reasons for conducting the review
• Explain how your appraisal is organized
• Highlight your work’s objective i.e., what you will cover
• You can use the same studies whenever they are needed to explain a specific subject
• Repeat the major themes and their underlying topics until you have fully described each one of them
• Explain what your review contributes to the field
• Identify the strengths and weaknesses of studies
• Describe the gaps you have located
• State the next steps for research to solve the identified issues

How to Write a Literature Review Outline

It is not easy to write an outline for a literature review, particularly if this is your first time. However, don’t be discouraged because like all other formal tasks you have done up to now, preparing an outline successfully necessitates following a correct procedure and organization.  With that in mind, we offer a step-by-step guideline on how to outline a literature review. Follow the process below to create an excellent piece.

• Select a topic. The initial step entails picking a topic of interest or a theme you are knowledgeable about. Choosing something you know helps in identifying relevant studies, which makes the writing process easier and more exciting. Focus on current and well-researched subjects as this makes finding sources less stressful. Also, be certain that you narrow down your issue to ensure it is specific and can be reviewed meaningfully.
• Search the body of literature. When you have a theme, the next step is identifying relevant studies related to your topic as you continue preparing your literature review outline. Limit your exploration to reliable databases such as JSTOR , NCBI , EBSCO , or Elsevier among others to find trusted sources. Your school library is also a very good place for searching manuscripts. If you are unsure about this process, ask a librarian or your professor for assistance. Remember to focus on useful and recent manuscripts not older than 5 years unless the instructions state otherwise or your topic requires earlier articles. The number of documents depends on your task guidelines. After selecting documents for your outline, evaluate them to see if they are applicable to your subject.
• Create a structure. To write a literature review outline effectively, you need to develop a well-organized and proper structure. Use one of the approaches discussed previously to organize your information. However, before starting, ensure that you understand how to begin your outline by using the created sketch to identify the main arguments to be included in it.
• Identify key concepts and themes. You also need to understand the arguments presented in your sources. Achieving this requires that you read all the texts you found repeatedly to digest and grasp their arguments. Be selective at first by looking at important sections such as abstracts , summaries, discussions , and conclusions to get an idea of point of views. Take notes of the main facts you find as this will assist in incorporating relevant texts into your work. After gaining insights into the major points of a study, you can now engage in deeper reading by covering all sections in detail.
• Compose an outline for a literature review. At this point, you can fill in your details to the sketch you created earlier by figuring out the arguments that are applicable to various sections. Your work now is simply to follow and maintain the structure you developed and draft your outline. Remember to proofread your plan and eliminate grammatical or other errors. Note that the aforementioned stages are described in a linear fashion. In reality, you may need to reformulate, reorganize, or recheck information and make several adjustments to your lit review outline. Thus, it may be necessary to revise specific parts of your paper regularly before delivering the best piece.

Literature Review Outline Examples

Reading a literature review outline sample to grasp the key ideas about this type of work is also important. Carefully examining these examples helps you gain insights into how well-structured pieces are prepared. Remember to check samples concerning your field of study to avoid confusion when developing your own. Additionally, your institution may have specific requirements for what you should cover. Thus, use the following samples of literature review outlines to augment your knowledge. Literature review outline example 1

Literature Review Outline Writing Tips

Now that you have a good idea about developing an outline for a literature review, it is important to provide you with additional useful information. Remember that you must cover everything stated in your instructions and clarify things you are not sure of. Here are the essential tips to keep in mind:

• Structure Develop a cohesive and logical structure as this allows you and others to easily understand which points are covered.
• Topic Highlight your topic first to demonstrate what your work is about.
• Format Ensure that you use an appropriate listing format to highlight major sections and their subheadings when writing a literature review outline. You can use different number layouts for the main sections and different listing designs for their subheadings. Regardless of your choice, be consistent throughout the paper.
• Ideas Each bullet list or paragraph should deal with one idea.
• Sections Ensure that all sections are linked to each other logically or your paper flows coherently.
• Citations Include in-text citations of information borrowed from outside studies to support your points.

FAQ About Literature Review Outline

1. how long is a literature review outline.

The length of a literature review outline depends on your work’s scope, type, and needed details. Comprehensive works such as thesis and dissertations may necessitate lengthier plans than class assignments. Generally, an outline takes a single page. However, there is no formula for how long this section should be. Use your judgment and consult your instructor regarding what is expected.

2. How to write a good literature review outline?

An outline for a literature review should not just summarize essential information. Rather, it should develop an argument by identifying ideas about your topic and their evolution in the academic discourse of relevant studies. A good outline should also mention any theoretical conflicts and methodological weaknesses found in sources.

3. What is a literature review outline purpose?

A literature review outline offers an overview of readings on a specific topic to help you establish a stand in your study field. Another purpose of this writing is to provide a reader with a view of past research. This shows your audience which direction the scholarly debate about a particular theme is heading in the context of current studies.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Organizing and Writing the Review

Organizing the review, writing the review, online resources.

After selecting the citations for inclusion into the review, it is time to outline and organize the literature review.  There are three basic components of a literature review: Introduction, Body, and Conclusion. Once the details of the outline are complete: it is time to write the literature review chapter of the research paper.   

Introduction to the review.   It should be brief, describing the body of the literature review in terms of format and logical structure. This covers areas such as the research problem, methodology, and the literature that addresses the context of the research study.

Body of the Literature Review . It serves as the logical structure for describing the study’s conceptual or theoretical frameworks. It should cite seminal studies regarding the research problem.  This is where the reviewer can take the liberty of synthesizing what you learned during the course of the literature search. If using subheadings to organize your content in the literature review, then divide by category.

The reviewer may find it useful to format subdivisions of the review. Below are some common subheadings that can divide the review into categories:

• Methodology
• Research findings

Conclusion.   It should also be brief succinctly summarizing what the researcher learned from the review and how it supports the underpinnings of the research study, identifies gaps in the literature and how it justifies the research study.

Writing the Review  You completed all phases in the process. It is time to write the literature review for your research paper. 

Here are a few tips for writing the review

Tip #1:  Know your audience Before writing, identify your audience: who reads the publication where you are submitting your manuscript?

Tip #2:  Avoid jargon Especially if writing for a general audience. Do not use extravagant words.

Tip #3: Keep paragraphs short Pare down excessive wordage when possible. Remember: brevity of content.  Keep review logical structure intact when writing.

Tip #4 : Use subheadings to clarify and lend coherence to review structure Subheadings help organize the review Use subheadings to drill down concepts you cover in the review.

        Tip #5: Focus and preserve continuity Stay on point, keep your focus, and do not stray.

Tip #6: Sustain logical flow Remember, the logical structure of your paper, makes your case in all instances. 

Tip #7: Avoid quotations Use only in rare instances. Always use paraphrasing whenever possible.

Tip #8:   Do not cite references you have not read! If you have not read the article, then DO NOT cite it.

Tip #9:   Use prudence in citing number of studies used Do not cite every source: only sources directly relevant.

Your goal: The reader, upon having read the literature review, should have confidence the author has a thorough understanding of the research topic; the reader has an appreciation of the research problem covered in the study through a grounding of the literature review.

1. Organizing Principles

A literature review is a piece of discursive prose, not a list describing or summarizing one piece of literature after another. It should have a single organizing principle:

• Thematic - organize around a topic or issue
• Chronological - sections for each vital time period
• Methodological - focus on the methods used by the researchers/writers

• Learn How to Write a Review of the Literature This guide is part of the Writer's Handbook provided by the Writing Center at the University of Wisconsin-Madison

2. Structure of the Literature Review

Although your literature review will rely heavily on the sources you read for its information, you should dictate the structure of the review. It is important that the concepts are presented in an order that makes sense of the context of your research project.

There may be clear divisions on the sets of ideas you want to discuss, in which case your structure may be fairly clear. This is an ideal situation. In most cases, there will be several different possible structures for your review.

Similarly to the structure of the research report itself, the literature review consists of:

• Introduction

Introduction - profile of the study

• Define or identify the general topic to provide the context for reviewing the literature
• Outline why the topic is important
• Identify overall trends in what has been published about the topic
• Identify conflicts in theory, methodology, evidence, and conclusions
• Identify gaps in research and scholarlship
• Explain the criteria to be used in analysing and comparing the literature
• Describe the organization of the review (the sequence)
• If necessary, state why certain literature is or is not included (scope)

Body - summative, comparative, and evaluative discussion of literature reviewed

For a thematic review:

• organize the review into paragraphs that present themes and identify trends relevant to your topic
• each paragraph should deal with a different theme - you need to synthesize several of your readings into each paragraph in such a way that there is a clear connection between the sources
• don't try to list all the materials you have identified in your literature search

From each of the section summaries:

• summarize the main agreements and disagreements in the literature
• summarize the general conclusions that have been drawn
• establish where your own research fits in the context of the existing literature

5. A Final Checklist

• Have you indicated the purpose of the review?
• Have you emphasized recent developments?
• Is there a logic to the way you organized the material?
• Does the amount of detail included on an issue relate to its importance?
• Have you been sufficiently critical of design and methodological issues?
• Have you indicated when results were conflicting or inconclusive and discussed possible reasons?
• Has your summary of the current literature contributed to the reader's understanding of the problems?

3. Tips on Structure

A common error in literature reviews is for writers to present material from one author, followed by information from another, then another.... The way in which you group authors and link ideas will help avoid this problem. To group authors who draw similar conclusions, you can use linking words such as:

• additionally

When authors disagree, linking words that indicate contrast will show how you have analysed their work. Words such as:

• on the other hand
• nonetheless

will indicate to your reader how you have analysed the material. At other times, you may want to qualify an author's work (using such words as specifically, usually, or generally ) or use an example ( thus, namely, to illustrate ). In this way you ensure that you are synthesizing the material, not just describing the work already carried out in your field.

Another major problem is that literature reviews are often written as if they stand alone, without links to the rest of the paper. There needs to be a clear relationship between the literature review and the methodology to follow.

How to Outline a Literature Review in 5 Steps

Table of contents

Have you ever had to write a literature review, not knowing what it is or how to write it, and then failed miserably on paper and in the eyes of your professor?

But first - why should one have to write a stellar literature review ?

Yes, it absolutely does!

The purpose of writing a literature review is to summarize and analyze the ideas and concepts of the author, without bringing your personal opinions and ideas into the review.

In this article, you will learn how to outline a literature review in five simple steps.

What are the Elements of a Literature Review Outline

The objective of a literature review is to identify a central trend, theme, principle, or concept that exists in the publication. This gives the plot meaning and highlights the significance of the topic within the specific subject area, which eventually ties the entire text together.

Literature reviews help in finding the relationship between two existing ideas and recognize major gaps and controversial elements within the topic.

The best way to deliver a top-notch literature review is to construct a well-structured outline.

3 Key Elements of a Literature Review Outline

Introduction.

The introduction of this paper should give a basic gist about your topic, have a strong thesis statement, and should establish the purpose of writing about your chosen topic.

Additionally, you should also include your point of view about the subject matter as well as the process or methodology that you’ll use to frame your literature review.

It is also a good idea to write the outcome you would expect to see by the end of your paper, for your professor to understand what you want to achieve from this.

The body paragraph of a literature review can be approached using different approaches. This portion of the review analyzes and interprets the different findings that relate to the literature, as well as includes the central theme that ties it together as a whole.

Always remember to use transition words, as well as subheadings, to make it easier for your professor to be able to understand the systematic flow of words.

Here are three of the most important ones that have been used to effectively structure the body paragraph of a literature review:

Chronologically

This approach is the simplest as you write the review based on the overall timeline, which starts at the beginning, and to the end.

In this approach, you can identify the development and growth of the chosen topic or a particular concept that you have examined over time. Keep in mind not to list down all the events in order, but to rather analyze important patterns, major themes, or key turning points in chronological order.

Thematically

Very different from the timeline approach, in this, you are required to examine, elaborate, and find a link between your sources and your chosen literary text.

The thematic approach revolves around the central issue or dispute, which is organized into subsections that address each aspect of the issue(s). These are analyzed in-depth and are time-consuming.

Methodologically

This type of approach is to understand the methods used to define or analyze a certain concept. By presenting the methods, you can compare them based on the severity, the sociological or cultural impacts, the qualitative or quantitative nature, the ethicality of the literature, and so on.

Summarize all your important points into a short paragraph, point out the strengths and weaknesses that you’ve gathered after researching the literature you analyzed, and emphasize the significance of writing a literature review on this chosen text.

5 Steps to Outline a Literature Review

Now that you know what goes into a literature review outline let’s take a look at how you can outline a literature review in five steps.

Narrow down on your topic

Before you start looking for literary texts to analyze, you need to figure out a clear and defined topic . Based on this topic, you can start searching for relevant literature that surrounds your chosen topic or the question that is to be analyzed.

During the search for your literature review topic, consider subject matters that are interesting to you or something that you would want to know in-depth about. You can also look for popular texts that could have multiple sources to work with.

To make this process easier, you should:

• Start writing down keywords that are related and relevant to your topic of choice. List any synonyms or related terms that you think would help in narrowing down your topic. As you keep searching for your literature, you can add any other keywords that come your way.
• Ask yourself questions and brainstorm topic ideas that can lead to you figuring out your chosen topic, or talk to your professor if you require their guidance.
• Try mapping out the concepts for your outline by creating a graphic map with all the ideas and concepts that you would want to include in the review. Make it a point to incorporate all of these ideas while writing your literature review.

Review relevant sources

When you have your topic picked out, the first thing you should do is use your compiled list of keywords to search for relevant literature and sources. At this time, it is crucial to use trusted sources like libraries, published research papers , and online databases.

After finding credible sources for your literature review, take a minute to see if your topic is actually related to the sources that you’ve found. Assess these sources and prioritize them according to what is relevant, what fits, and what doesn’t.

Map out a structure

For outlining the body of your literature review, multiple approaches can be used to create a proper, well-organized structure, which we have discussed in the above section.

Before you begin, you should have a rough idea about how you would wish to start your literature review. No academic paper should be attempted before having a proper plan for framing the content of your paper.

Through this organized skeleton structure of the paper, you can quickly and easily identify the points that you want to be included.

Identifying key themes and patterns

Read your literature multiple times to understand the connections and the relationship between the sources you’ve used and the text that needs to be analyzed.

This will help you have a solid knowledge about the subject before you start writing, as well as create a proper flow of ideas to make writing your literature review a simpler process.

Some of the things you need to look out for during this process include the following:

• themes and concepts that recur throughout the literature;
• debates or contradictions that include conflicts around the theories present in the text;
• gaps and weaknesses in the literature that needs to be filled or addressed;
• trends and patterns that are prevalent and are an important portion of the review.

Working on this point will help show your professor that you can contribute a major portion of ideas and knowledge through your research, to the already existing content.

Here’s a useful video by Scribbr on identifying themes in literature

Write your draft and proofread

At this point, you can start writing your literature review. Since you have all your sources, citations, a complete detailed outline, and extra notes, figuring out which point needs to go in which section will become a much smoother process.

All you need to do now is to follow your plan and maintain the structure that you have created to draft your review.

Most students neglect to revise and proofread their papers, which can cause unnecessary, avoidable errors that bring down the entire quality and authority of your submission. Make sure to check for spelling and grammatical mistakes as well as the flow of your sentences.

Check to make sure that there is no portion in your literature review that has been plagiarized . This can happen if you have failed to cite a source or reference or if you have used (copied) phrases directly from another source.
