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.

Chapter 5: The Literature Review
5.4 The Five ‘C’s of Writing a Literature Review
To help you frame and write your literature review, think about these five c’s (Callahan, 2014):
- Cite the material you have referred to and used to help you define the research problem that you will study.
- Compare the various arguments, theories, methods, and findings expressed in the literature.For example, describe where the various researchers agree and where they disagree. Describe the similarities and dissimilarities in approaches to studying related research problems.
- Contrast the various arguments, themes, methods, approaches, and controversies apparent and/or described in the literature. For example, describe what major areas are contested, controversial and/or still in debate.
- Critique the literature. Describe which arguments you find more persuasive and explain why. Explain which approaches, findings, and methods seem most reliable, valid, appropriate, and/or most popular and why. Pay attention to the verbs you use to describe what previous researchers have stated (e.g., asserts, demonstrates, argues, clarifies, etc.).
- Connect the various research studies you reviewed. Describe how your work utilizes, draws upon, departs from, synthesizes, adds to or extends previous research studies.

The 5 C Guidelines
Vector Design by Vecteezy.com
Producing good academic writing is a difficult skill to master, and writing for an academic audience is different than writing for other audiences.
As an academic writer, you must approach topics differently than you might as a journalist or creative author, and you must emphasize certain skills, such as writing clearly, and ignore other skills that you might have been taught in other contexts, such as using expressive imagery.
To introduce you to this world of academic writing, in this chapter I suggest that you should focus on five hierarchical characteristics of good writing, or the “5 Cs” of good academic writing, which include Clarity, Cogency, Conventionality, Completeness, and Concision. I will now explain each of these in more depth and then discuss tensions between them in writing for different academic audiences.
"Ambiguity is very interesting in writing; it's not very interesting in science." — Janna Levin
Many of us were taught in writing courses that ambiguity and obfuscation of meaning are laudable, because they make our writing seem more complex, deep, and witty. And many of our favorite novelists likely use ambiguity and other tricks to make their writing seem mysterious and complex.
In academic writing, though, these practices simply suggest that you don’t know what you’re talking about. For academics, writing is a way of uncovering truths and realities of the social and physical world, so we should say what we mean. We should make it clear, and say it so that it is impossible for our audience to misunderstand. If your imagined reader ever has to squint her eyes and muse “I wonder what the author really meant by this,” then you have failed. If your imagined reader ever smiles to herself and chuckles at your brilliant wordplay, then you have failed.
This is not to say that academic writing must be joyless and stodgy. It can be witty. It can be deep. But academic depth and wit come from the ideas portrayed through the words, not the words themselves. Too often, writers use ambiguity to hide sloppy thinking and beautiful language to hide destitute ideas. If you say something that could potentially be misunderstood, explain it. If a simpler word will do in place of a more complex one, then use the simple word. Don't be afraid of laying out complex ideas across multiple sentences or paragraphs, but use the space available to you to open up your mind to your reader — what exactly you are thinking, how you are thinking about it, and why.
If you use jargon, technical terms, or initialisms, then you should define or operationalize them. Defining a term means that you are relying upon someone else’s explanation of what the term means and are sticking with it (e.g., “Marwick defines ‘social media’ as…”). Operationalizing a term means that you are using a term that might mean multiple things but you are deciding to only use it in a very finite and specific manner (e.g., “In this paper, I use the word ‘engagement’ to mean…”).
In the case of initialisms, no reader should be expected to know what a PBL, SNS, LMS, CMS, or PBIS is by virtue of the letters themselves, and often even technical initialisms might have multiple meanings (e.g., PBL in education might refer to “project-based learning” or “problem-based learning”). So, when you use initialisms in your writing, define them at the outset (e.g., “positive behavioral interventions and supports (PBIS)”).
If you find yourself repeating the same words over and over again, that’s okay; don’t use variety in your language just for the sake of variety, because in highly technical academic fields every word carries with it technical baggage that you may not intend. If I’m talking about a “curriculum,” then I shouldn’t swap this out with “program,” “module,” “subject,” or “materials” just because I’m tired of saying “curriculum;” each of these words means something very different, and using these terms interchangeably just shows my reader that I don’t understand the differences between them.
In short, other types of writing often rely upon ambiguity and obfuscation to prevent their underlying thought processes from being examined, but examination of these processes is the whole purpose of academic writing. We are not poets, politicians, or preachers, whose primary goals are to be convincing or mystical; rather, we are fellow learners that can only learn together insofar as we can clearly reason together through a dialogic process of clear writing.
"Logic is the beginning of wisdom, not the end." — Leonard Nimoy
Your writing should follow a logical pattern or argument. Arguments generally follow a pattern of identifying one or more assumptions, providing evidence, and drawing a conclusion, such as:
- Assumption - Test creators should design tests to be equitable to all learners who may represent various demographic differences (e.g., race, ethnicity, gender);
- Evidence - Specific research studies show that some prominent tests exhibit inequitable outcomes for students based on race and ethnicity;
- Conclusion - Therefore, test creators should seek to understand why such tests are biased toward some students and should seek to remedy this issue.
Once a conclusion is drawn, it can then be used as an assumption for a subsequent argument. This means that the overarching argument for a paper actually consists of many micro-arguments made throughout the paper that build upon one another like bricks in a wall. Essentially, each paragraph in an academic paper should be treated as its own separate argument, and these arguments then build off of each other to construct the overarching argument.
To help reveal your logical structure, each paragraph should generally represent its own argument. It should start with a topic sentence, provide evidence, and then draw a conclusion that you then build upon in the next paragraph. This is what people often refer to as logical flow: moving from one idea to another without any unsubstantiated gaps.
Since you must substantiate each claim that you make in an academic paper, you should also be careful not to overstate claims (e.g., using superlative language) and not to make claims that you cannot provide evidence for. Oftentimes, this is done by toning down language (e.g., "project-based learning can be an effective pedagogical strategy" [toned down] vs. "project-based learning is the best pedagogical strategy" [superlative]) and using helping verbs, such as may, can, and might (e.g., "social media use may contribute to student depression" vs. "social media make kids depressed"). By toning down your language, you introduce possibilities for doubt (which academics should always be open to) and also prevent your argument from being invalidated by a single counter-instance (e.g., "my kid uses social media and is not depressed, therefore your argument is invalid").
Conventionality
"Writing [without structure] is like playing tennis with the net down." — Robert Frost
In order to understand each other and to know what to expect when we are reading a new manuscript, we need some conventions to provide uniformity. If every article you read had a unique structure, formatting, spacing, capitalization, font size, style, tone, and so forth, you would have increased difficulty comparing it to other work that had gone before.
However, if every time you approach a new piece of writing you know what to expect and where to find it, you will be able to more efficiently recognize where to go and what to look for in the paper. Rather than hunting for the research question, you will know that it will be found right before the methods section and that results will be provided right after that section. Similarly, when you see a bolded and centered line of text, you will know that this means that a new top-level (H1) section is beginning and are not left to wonder why the author made such a bold stylistic choice.
For these reasons, groups of academics have sets of guidelines that they agree to follow, and in our field we follow the American Psychological Association’s (APA) Handbook (version 6). That handbook covers everything from structure and formatting to style and tone, and theses, dissertations, and class projects require students to follow these same guidelines to help ensure that student work is written in a way that will allow it to be published to a wider audience.
APA Template
To assist you in following APA guidelines, you can access this Google Document that has proper APA heading formats built into it. Then, click on the Styles dropdown > Options and save the APA styles as your default styles, thereby making any new documents that you create in Google Drive follow the APA conventions.
Completeness
"Our duty is to believe that for which we have sufficient evidence, and to suspend our judgment when we have not." — John Lubbock
Since the goal of academic work is to inform as broad an audience as possible and to stand up under the scrutiny of diverse sets of eyes, you must flesh out your writing to address all of the major questions and doubts that your readers might have. Thus, you must not only make an argument that might be convincing to a few people, but you must include sufficient detail and explanation to allow your writing to hold under the scrutiny of the most critical reader. That is, you must write for your greatest critic, not your greatest fan.
This is why academic publishing relies upon peer review. The assumption of peer review is that the best way to ensure quality of writing is to put an author’s work in the hands of dispassionate, unbiased, and diverse experts who typically do not know the identity of the author. This allows reviewers to be honest in their feedback and prevents them from relying upon their personal relationships with or knowledge of the author to fill any gaps (e.g., “I’ve heard of Dr. Avila, and she’s done great work before, so I’m assuming that she did good work here, too”). Rather, every piece of academic writing must stand or fall on its own merits and not on the author’s prior quality of work or reputation.
To do this, you must be explicit and detailed, assume that your reader does not know or trust you as the author, and treat every piece of academic writing as a completely self-contained, self-sustaining, self-validating artifact.
"Brevity is the soul of wit."— William Shakespeare
Most journals in education and other social sciences have strict article word limits of 4,000 to 7,000 words, or roughly 20 to 30 double-spaced pages. This historically has been done to accommodate publishing limitations, because printing pages in a journal is expensive, but even in a digital world, with practically zero publishing costs for adding additional words, imposing limits helps to reduce information overload on readers and to drive more readers to your work.
After all, a moderately-interested reader is much more likely to read a ten-page synopsis of your dissertation than the 200-page document itself, and only the most devoted of readers will stick with it after 20 pages or so. This means that you as the author must not only meet all of the requirements established by the previous guidelines, but you must do it on a strict word budget that avoids unnecessary detail or repetition.
Tensions and Relative Importance
As you’ve probably guessed by this point, the demands of each of these guidelines sometimes conflict with one another. For instance, being complete might mean that you are not very concise, and being clear might reveal the irrationality or poor cogency of your argument. At such times, you must prioritize the guidelines to determine which to emphasize and which to ignore.
Depending on the type of academic writing you are doing, the way that you prioritize guidelines may vary. For instance, a journal article will normally value concision over completeness, due to publishing word limits and trying to make the article as accessible as possible to a wide audience, while a systematic literature review for a thesis or dissertation will do the opposite, requiring students to reveal all of their understanding of their topic and how it is situated within the broader field so that their committees can be assured that they actually know what they are talking about.
Similarly, a quantitative empirical paper will rely heavily upon the conventions established by the paradigm (e.g., p-values, effect sizes), while a qualitative empirical paper will need to provide completeness in its descriptions to allow for trustworthiness and at times ignore conventions. Theoretical papers will also often necessarily defy some conventions in favor of laying out a clear and cogent argument, because the proposed ideas will be new and will not neatly fit within existing reporting approaches but will nonetheless need to be argued in a reasonable and compelling manner.
All this is to say that though these guidelines are all important, their relative importance to one another varies by the context of the writing as determined by purpose, audience, and methods.
Relative Importance of the 5 Cs in Different Settings
By focusing on these 5 Cs and each of their relative importance for your writing context, you can begin to approach your own work in a manner that is systematic and self-reflective. If writing a thesis, for instance, I should start by asking myself "Am I including all pertinent information and details? Is my meaning clear? Is my logic sound? Am I following APA guidelines? And am I careful not to repeat myself or belabor my point?" If writing a theoretical argument for a journal, on the other hand, I should ask myself "Am I within the word limit for the journal? Am I following the journal's stylistic guidelines? Is my argument strong? Is my meaning clear? And do I cover everything that I need to in order to preempt any concerns?"
When asking these questions, something always has to give, such as cutting that explanatory paragraph to get an article under the journal’s required word limit or adding an additional paragraph to make it clear to your thesis readers that you understand the implications of what you’re saying. Through it all, however, each of these guidelines is generally important to follow, and you can only justify ignoring one temporarily in those cases where tensions exist and your intended audience requires you to prioritize another guideline in its place.

by Yen Cabag | 5 comments
If you’re a college or graduate student, you will likely have to write a thesis or dissertation. As an employee in a corporate office, you may also be called on to do some research.
Writing an academic paper doesn’t have to be daunting when you know the different components, why they matter, and how to write them. The literature review is one of the first steps to writing an academic paper, and also one of the most important.
What Is a Literature Review?
A literature review is a compilation of scholarly sources that discuss the topic you are researching. Because it serves as an overview of existing research, a literature review lets you highlight relevant principles and methods, while also identifying gaps in whatever research currently exists. This builds a strong foundation for everything else in your paper.
Note that a literature review may also be a stand-alone paper you are assigned to write. This is the case when you are called on to look into the current state of research around your topic, and to analyze and synthesize your findings.
Writing a literature review requires you to collect, evaluate, and analyze existing publications, including journal articles and books that relate to the research question you have chosen.
Purpose of a Literature Review
The literature review is an important part of the research process. It serves the following critical functions:
- It helps familiarize you with the topic.
- It helps you construct a theoretical framework and come up with a methodology for your research.
- It lets you place yourself within the context of other theorists and researchers.
- It shows readers how your paper adds to an existing debate or addresses a given gap that you highlight from existing research.
In addition, if you’re a nonfiction author, you might want to write up a literature review to survey the existing research surrounding your topic, so you can be sure to fill any gaps and address new reader needs.
What Should Be Included in the Literature Review?
Your literature review should include the following information:
- All relevant findings related to your subject, with their sources properly cited
- Any existing debates or controversial discussions
- Any gaps in the existing research that you can meet in your research
How to Write a Literature Review
Since the literature review forms the backbone of your research, writing a clear and thorough review is essential. The steps below will help you do so:
1. Search for relevant information and findings.
In research, information published on a given subject is called “literature” or “background literature.” Assuming you already have a clearly-defined topic, the first step you need to take is searching for the relevant literature.
Before the boom of the internet, searching for relevant literature involved going to the library and weeding through tons of journal articles or research papers on a subject. These days, you can quickly access these articles and other publications with a simple internet search.
Because of this, your first step will include listing down the keywords that will help you find the results you need. List down everything that is related to your research topic. For example, if your research question is “What effect does social media have on depression?” you might include specific keywords like “Facebook” and “Instagram” to find more results.
Also, because the Internet is overflowing with information and not all of it may be relevant, you will have to learn how to do an efficient search. This includes learning technical search phrases that let you refine your results.
One of the most important tools is the term “site:” which lets you specify which website to search in.
For example, when you type “site: www.usa.gov ” followed by a space and then the keyword, the search will be done automatically only on the U.S. Data and Statistics website.
Other tools include what we call boolean operators or search terms, which can help you focus your search:
- AND – helps you find sources that have more than one keyword
- OR – helps you find sources containing one of a given number of keywords
- NOT – lets you exclude results that contain certain keywords
Some examples of useful databases where you can search for articles and journals are:
- Google Scholar
- Project Muse – for social sciences and humanities topics
- Medline – for biomedicine and life sciences research subjects
- EconLit – for economic research
- Inspec – for computer science, physics, and engineering topics
2. Evaluate your sources and select the most relevant ones.
Because you will not have the time to read every single article you find, you need to evaluate which sources will be the most relevant to your research question. First, look through the most credible sources, and also be sure to read major theories and landmark studies.
For publications that may not be too clear in terms of credibility or undisputed authority, the following questions can help you evaluate them:
- What problem does this article address?
- What are its key concepts and how does the author define them?
- What key theories, models, or methods does the author use? Do they use established frameworks or a more innovative slant?
- What conclusions does the author reach in this study?
- How does this article relate to other publications in the same field? Does it add to, confirm, or refute other articles?
- How does this article add to your understanding of your research question? What key insights and arguments can you glean from it?
- What are its strengths and weaknesses?
- How many times has it been cited on Google Scholar? (This helps you determine how influential the article is in its field: the higher the citation count, the greater its influence.)
3. Identify key topics, debates, and research gaps.
After you’ve compiled your sources, it’s time to start organizing them. You can do this by first identifying any underlying themes. These can come in the form of:
- Patterns or trends: Are there approaches that are becoming more or less well-known over time?
- Themes: Are there recurring concepts that stand out to you from all the literature you compiled?
- Conflicts, contradictions, or debates: In what areas do your sources disagree?
- Landmark publications : What other study or theory is greatly impacting the way the field is developing?
- Research gaps: What areas have not been covered in detail in the background literature you compiled? What weaknesses do you think should be addressed in your paper?
4. Prepare your outline.
For academic papers, it’s always best to formulate your outline before you begin writing. This helps you organize your thoughts and all your findings into a coherent whole.
After all, you don’t want your literature review to look like a shopping list that simply compiles every piece of information you found, without any thought as to how they all come together.
Your outline should include an introduction, main body, and conclusion.
5. Write the contents of your literature review.
With your outline in place, you can now start to write your literature review.
For the introduction, establish the purpose of your literature review. Here you can explain whether the literature review is part of a larger work or if it’s a stand-alone piece.
In the body of the paper, you will start to elaborate on the points you put in your outline. Use subheadings to make the paragraphs clearer.
These additional tips will also help you make a literature review that adds value to others:
- Summarize your findings: When writing your literature review, don’t just copy and paste whatever you find. Summarize and paraphrase as much as possible.
- Analyze: Then, add your own analysis. A literature review is valuable because of the insights you provide.
- Evaluate critically: Be sure to remain as objective as possible.
- Structure your paragraphs: Keep each paragraph to one main theme, and include transitional sentences to make each paragraph flow neatly to the next.
- State your references: As you write, be sure to note down which sources gave which ideas or findings. Depending on the requirements, you can use the AP Style or Chicago Style of referencing.
How Do You Structure a Literature Review?
You can structure your literature review in the following ways:
- Thematic : In a thematic outline, you will be compiling your information to revolve around a specific theme. Different parts of your research may go into different subsections that focus on certain parts of your topic.
- Chronological : This approach lets you show the development of your topic over time. While this is helpful in showing how theories change, be sure to add your own analysis of patterns, turning points, or debates, showing how they helped shape where the field is going. One way of doing this is interpreting how or why the specific developments happened.
- Methodological: In this format, you will be looking at the different research methods your sources used, comparing how they arrived at conclusions or recommendations. You can discuss how and why the different sources opted for those methods, perhaps looking at whether the source is sociological, cultural, or historical.
- Theoretical: A theoretical framework lets you focus on discussing the different models, theories, and key concepts surrounding your topic.
Writing a Lit Review
Writing a literature review does not have to be a tedious process as long as you know what you need to do.
Knowing how to choose sources will save you a lot of time and energy, and analyzing the information as you read it will also let you write more efficiently, resulting in a literature review that is useful for your own research.

This handout will explain what literature reviews are and offer insights into the form and construction of literature reviews in the humanities, social sciences, and sciences.
Introduction
OK. You’ve got to write a literature review. You dust off a novel and a book of poetry, settle down in your chair, and get ready to issue a “thumbs up” or “thumbs down” as you leaf through the pages. “Literature review” done. Right?
Wrong! The “literature” of a literature review refers to any collection of materials on a topic, not necessarily the great literary texts of the world. “Literature” could be anything from a set of government pamphlets on British colonial methods in Africa to scholarly articles on the treatment of a torn ACL. And a review does not necessarily mean that your reader wants you to give your personal opinion on whether or not you liked these sources.
What is a literature review, then?
A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period.
A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant.
But how is a literature review different from an academic research paper?
The main focus of an academic research paper is to develop a new argument, and a research paper is likely to contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.
Why do we write literature reviews?
Literature reviews provide you with a handy guide to a particular topic. If you have limited time to conduct research, literature reviews can give you an overview or act as a stepping stone. For professionals, they are useful reports that keep them up to date with what is current in the field. For scholars, the depth and breadth of the literature review emphasizes the credibility of the writer in his or her field. Literature reviews also provide a solid background for a research paper’s investigation. Comprehensive knowledge of the literature of the field is essential to most research papers.
Who writes these things, anyway?
Literature reviews are written occasionally in the humanities, but mostly in the sciences and social sciences; in experiment and lab reports, they constitute a section of the paper. Sometimes a literature review is written as a paper in itself.
Let’s get to it! What should I do before writing the literature review?
If your assignment is not very specific, seek clarification from your instructor:
- Roughly how many sources should you include?
- What types of sources (books, journal articles, websites)?
- Should you summarize, synthesize, or critique your sources by discussing a common theme or issue?
- Should you evaluate your sources?
- Should you provide subheadings and other background information, such as definitions and/or a history?
Find models
Look for other literature reviews in your area of interest or in the discipline and read them to get a sense of the types of themes you might want to look for in your own research or ways to organize your final review. You can simply put the word “review” in your search engine along with your other topic terms to find articles of this type on the Internet or in an electronic database. The bibliography or reference section of sources you’ve already read are also excellent entry points into your own research.
Narrow your topic
There are hundreds or even thousands of articles and books on most areas of study. The narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good survey of the material. Your instructor will probably not expect you to read everything that’s out there on the topic, but you’ll make your job easier if you first limit your scope.
Keep in mind that UNC Libraries have research guides and to databases relevant to many fields of study. You can reach out to the subject librarian for a consultation: https://library.unc.edu/support/consultations/ .
And don’t forget to tap into your professor’s (or other professors’) knowledge in the field. Ask your professor questions such as: “If you had to read only one book from the 90’s on topic X, what would it be?” Questions such as this help you to find and determine quickly the most seminal pieces in the field.
Consider whether your sources are current
Some disciplines require that you use information that is as current as possible. In the sciences, for instance, treatments for medical problems are constantly changing according to the latest studies. Information even two years old could be obsolete. However, if you are writing a review in the humanities, history, or social sciences, a survey of the history of the literature may be what is needed, because what is important is how perspectives have changed through the years or within a certain time period. Try sorting through some other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to consider what is currently of interest to scholars in this field and what is not.
Strategies for writing the literature review
Find a focus.
A literature review, like a term paper, is usually organized around ideas, not the sources themselves as an annotated bibliography would be organized. This means that you will not just simply list your sources and go into detail about each one of them, one at a time. No. As you read widely but selectively in your topic area, consider instead what themes or issues connect your sources together. Do they present one or different solutions? Is there an aspect of the field that is missing? How well do they present the material and do they portray it according to an appropriate theory? Do they reveal a trend in the field? A raging debate? Pick one of these themes to focus the organization of your review.
Convey it to your reader
A literature review may not have a traditional thesis statement (one that makes an argument), but you do need to tell readers what to expect. Try writing a simple statement that lets the reader know what is your main organizing principle. Here are a couple of examples:
The current trend in treatment for congestive heart failure combines surgery and medicine. More and more cultural studies scholars are accepting popular media as a subject worthy of academic consideration.
Consider organization
You’ve got a focus, and you’ve stated it clearly and directly. Now what is the most effective way of presenting the information? What are the most important topics, subtopics, etc., that your review needs to include? And in what order should you present them? Develop an organization for your review at both a global and local level:
First, cover the basic categories
Just like most academic papers, literature reviews also must contain at least three basic elements: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper. The following provides a brief description of the content of each:
- Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
- Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
- Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?
Organizing the body
Once you have the basic categories in place, then you must consider how you will present the sources themselves within the body of your paper. Create an organizational method to focus this section even further.
To help you come up with an overall organizational framework for your review, consider the following scenario:
You’ve decided to focus your literature review on materials dealing with sperm whales. This is because you’ve just finished reading Moby Dick, and you wonder if that whale’s portrayal is really real. You start with some articles about the physiology of sperm whales in biology journals written in the 1980’s. But these articles refer to some British biological studies performed on whales in the early 18th century. So you check those out. Then you look up a book written in 1968 with information on how sperm whales have been portrayed in other forms of art, such as in Alaskan poetry, in French painting, or on whale bone, as the whale hunters in the late 19th century used to do. This makes you wonder about American whaling methods during the time portrayed in Moby Dick, so you find some academic articles published in the last five years on how accurately Herman Melville portrayed the whaling scene in his novel.
Now consider some typical ways of organizing the sources into a review:
- Chronological: If your review follows the chronological method, you could write about the materials above according to when they were published. For instance, first you would talk about the British biological studies of the 18th century, then about Moby Dick, published in 1851, then the book on sperm whales in other art (1968), and finally the biology articles (1980s) and the recent articles on American whaling of the 19th century. But there is relatively no continuity among subjects here. And notice that even though the sources on sperm whales in other art and on American whaling are written recently, they are about other subjects/objects that were created much earlier. Thus, the review loses its chronological focus.
- By publication: Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on biological studies of sperm whales if the progression revealed a change in dissection practices of the researchers who wrote and/or conducted the studies.
- By trend: A better way to organize the above sources chronologically is to examine the sources under another trend, such as the history of whaling. Then your review would have subsections according to eras within this period. For instance, the review might examine whaling from pre-1600-1699, 1700-1799, and 1800-1899. Under this method, you would combine the recent studies on American whaling in the 19th century with Moby Dick itself in the 1800-1899 category, even though the authors wrote a century apart.
- Thematic: Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For instance, the sperm whale review could focus on the development of the harpoon for whale hunting. While the study focuses on one topic, harpoon technology, it will still be organized chronologically. The only difference here between a “chronological” and a “thematic” approach is what is emphasized the most: the development of the harpoon or the harpoon technology.But more authentic thematic reviews tend to break away from chronological order. For instance, a thematic review of material on sperm whales might examine how they are portrayed as “evil” in cultural documents. The subsections might include how they are personified, how their proportions are exaggerated, and their behaviors misunderstood. A review organized in this manner would shift between time periods within each section according to the point made.
- Methodological: A methodological approach differs from the two above in that the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the “methods” of the researcher or writer. For the sperm whale project, one methodological approach would be to look at cultural differences between the portrayal of whales in American, British, and French art work. Or the review might focus on the economic impact of whaling on a community. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed. Once you’ve decided on the organizational method for the body of the review, the sections you need to include in the paper should be easy to figure out. They should arise out of your organizational strategy. In other words, a chronological review would have subsections for each vital time period. A thematic review would have subtopics based upon factors that relate to the theme or issue.
Sometimes, though, you might need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. Put in only what is necessary. Here are a few other sections you might want to consider:
- Current Situation: Information necessary to understand the topic or focus of the literature review.
- History: The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
- Methods and/or Standards: The criteria you used to select the sources in your literature review or the way in which you present your information. For instance, you might explain that your review includes only peer-reviewed articles and journals.
Questions for Further Research: What questions about the field has the review sparked? How will you further your research as a result of the review?
Begin composing
Once you’ve settled on a general pattern of organization, you’re ready to write each section. There are a few guidelines you should follow during the writing stage as well. Here is a sample paragraph from a literature review about sexism and language to illuminate the following discussion:
However, other studies have shown that even gender-neutral antecedents are more likely to produce masculine images than feminine ones (Gastil, 1990). Hamilton (1988) asked students to complete sentences that required them to fill in pronouns that agreed with gender-neutral antecedents such as “writer,” “pedestrian,” and “persons.” The students were asked to describe any image they had when writing the sentence. Hamilton found that people imagined 3.3 men to each woman in the masculine “generic” condition and 1.5 men per woman in the unbiased condition. Thus, while ambient sexism accounted for some of the masculine bias, sexist language amplified the effect. (Source: Erika Falk and Jordan Mills, “Why Sexist Language Affects Persuasion: The Role of Homophily, Intended Audience, and Offense,” Women and Language19:2).
Use evidence
In the example above, the writers refer to several other sources when making their point. A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid.
Be selective
Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the review’s focus, whether it is thematic, methodological, or chronological.
Use quotes sparingly
Falk and Mills do not use any direct quotes. That is because the survey nature of the literature review does not allow for in-depth discussion or detailed quotes from the text. Some short quotes here and there are okay, though, if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Notice that Falk and Mills do quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. But if you find yourself wanting to put in more quotes, check with your instructor.
Summarize and synthesize
Remember to summarize and synthesize your sources within each paragraph as well as throughout the review. The authors here recapitulate important features of Hamilton’s study, but then synthesize it by rephrasing the study’s significance and relating it to their own work.
Keep your own voice
While the literature review presents others’ ideas, your voice (the writer’s) should remain front and center. Notice that Falk and Mills weave references to other sources into their own text, but they still maintain their own voice by starting and ending the paragraph with their own ideas and their own words. The sources support what Falk and Mills are saying.
Use caution when paraphrasing
When paraphrasing a source that is not your own, be sure to represent the author’s information or opinions accurately and in your own words. In the preceding example, Falk and Mills either directly refer in the text to the author of their source, such as Hamilton, or they provide ample notation in the text when the ideas they are mentioning are not their own, for example, Gastil’s.

Revise, revise, revise
Draft in hand? Now you’re ready to revise. Spending a lot of time revising is a wise idea, because your main objective is to present the material, not the argument. So check over your review again to make sure it follows the assignment and/or your outline. Then, just as you would for most other academic forms of writing, rewrite or rework the language of your review so that you’ve presented your information in the most concise manner possible. Be sure to use terminology familiar to your audience; get rid of unnecessary jargon or slang. Finally, double check that you’ve documented your sources and formatted the review appropriately for your discipline. For tips on the revising and editing process, see our handout on revising drafts .

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.

Importance of a Good Literature Review
A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:
- Give a new interpretation of old material or combine new with old interpretations,
- Trace the intellectual progression of the field, including major debates,
- Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
- Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.
Given this, the purpose of a literature review is to:
- Place each work in the context of its contribution to understanding the research problem being studied.
- Describe the relationship of each work to the others under consideration.
- Identify new ways to interpret prior research.
- Reveal any gaps that exist in the literature.
- Resolve conflicts amongst seemingly contradictory previous studies.
- Identify areas of prior scholarship to prevent duplication of effort.
- Point the way in fulfilling a need for additional research.
- Locate your own research within the context of existing literature [very important].

Types of Literature Reviews
It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.
In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.
Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena 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 to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.
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 to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.
Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.
NOTE : Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style
I. Thinking About Your Literature Review
The structure of a literature review should include the following in support of understanding the research problem :
- An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
- Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
- An explanation of how each work is similar to and how it varies from the others,
- Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.
The critical evaluation of each work should consider :
- Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
- Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
- Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
- Persuasiveness -- which of the author's theses are most convincing or least convincing?
- Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?
II. Development of the Literature Review
Four Basic Stages of Writing 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.
Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. Roughly how many sources would be appropriate to include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5. Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.
III. Ways to Organize Your Literature Review
Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it will still be organized chronologically reflecting technological developments in media. The only difference here between a "chronological" and a "thematic" approach is what is emphasized the most: the role of the Internet in presidential politics. Note however that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point made. Note that this is the most common approach in the social and behavioral sciences. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.
Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.
Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:
- Current Situation : Information necessary to understand the current topic or focus of the literature review.
- Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
- History : The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
- Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed articles and journals.
- Standards : Description of the way in which you present your information.
- Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?
IV. Writing Your Literature Review
Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.
Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information but that are not key to understanding the research problem can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.
V. Common Mistakes to Avoid
These are the most common mistakes made in reviewing social science research literature.
- Sources in your literature review do not clearly relate to the research problem;
- You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
- Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
- Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
- Does not describe the search procedures that were used in identifying the literature to review;
- Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
- Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip
Break Out of Your Disciplinary Box!
Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.
Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.
Another Writing Tip
Don't Just Review for Content!
While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:
- How are they organizing their ideas?
- What methods have they used to study the problem?
- What theories have been used to explain, predict, or understand their research problem?
- What sources have they cited to support their conclusions?
- How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?
When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.
Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.
Yet Another Writing Tip
When Do I Know I Can Stop Looking and Move On?
Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:
- Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research? Does it forge a new path? Or, does is merely add more of the same thing being said?
- Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
- Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

How To Write An A-Grade Literature Review
3 straightforward steps (with examples) + free template.
By: Derek Jansen (MBA) | Expert Reviewed By: Dr. Eunice Rautenbach | October 2019
Quality research is about building onto the existing work of others , “standing on the shoulders of giants”, as Newton put it. The literature review chapter of your dissertation, thesis or research project is where you synthesise this prior work and lay the theoretical foundation for your own research.
Long story short, this chapter is a pretty big deal, which is why you want to make sure you get it right . In this post, I’ll show you exactly how to write a literature review in three straightforward steps, so you can conquer this vital chapter (the smart way).
Overview: The Literature Review Process
- Understanding the “ why “
- Finding the relevant literature
- Cataloguing and synthesising the information
- Outlining & writing up your literature review
But first, the “why”…
Before we unpack how to write the literature review chapter, we’ve got to look at the why . To put it bluntly, if you don’t understand the function and purpose of the literature review process, there’s no way you can pull it off well. So, what exactly is the purpose of the literature review?
Well, there are (at least) four core functions:
- For you to gain an understanding (and demonstrate this understanding) of where the research is at currently, what the key arguments and disagreements are.
- For you to identify the gap(s) in the literature and then use this as justification for your own research topic.
- To help you build a conceptual framework for empirical testing (if applicable to your research topic).
- To inform your methodological choices and help you source tried and tested questionnaires (for interviews ) and measurement instruments (for surveys ).
Most students understand the first point but don’t give any thought to the rest. To get the most from the literature review process, you must keep all four points front of mind as you review the literature (more on this shortly), or you’ll land up with a wonky foundation.
Okay – with the why out the way, let’s move on to the how . As mentioned above, writing your literature review is a process, which I’ll break down into three steps:
- Finding the most suitable literature
- Understanding , distilling and organising the literature
- Planning and writing up your literature review chapter
Importantly, you must complete steps one and two before you start writing up your chapter. I know it’s very tempting, but don’t try to kill two birds with one stone and write as you read. You’ll invariably end up wasting huge amounts of time re-writing and re-shaping, or you’ll just land up with a disjointed, hard-to-digest mess . Instead, you need to read first and distil the information, then plan and execute the writing.
Step 1: Find the relevant literature
Naturally, the first step in the literature review journey is to hunt down the existing research that’s relevant to your topic. While you probably already have a decent base of this from your research proposal , you need to expand on this substantially in the dissertation or thesis itself.
Essentially, you need to be looking for any existing literature that potentially helps you answer your research question (or develop it, if that’s not yet pinned down). There are numerous ways to find relevant literature, but I’ll cover my top four tactics here. I’d suggest combining all four methods to ensure that nothing slips past you:
Method 1 – Google Scholar Scrubbing
Google’s academic search engine, Google Scholar , is a great starting point as it provides a good high-level view of the relevant journal articles for whatever keyword you throw at it. Most valuably, it tells you how many times each article has been cited, which gives you an idea of how credible (or at least, popular) it is. Some articles will be free to access, while others will require an account, which brings us to the next method.
Method 2 – University Database Scrounging
Generally, universities provide students with access to an online library, which provides access to many (but not all) of the major journals.
So, if you find an article using Google Scholar that requires paid access (which is quite likely), search for that article in your university’s database – if it’s listed there, you’ll have access. Note that, generally, the search engine capabilities of these databases are poor, so make sure you search for the exact article name, or you might not find it.
Method 3 – Journal Article Snowballing
At the end of every academic journal article, you’ll find a list of references. As with any academic writing, these references are the building blocks of the article, so if the article is relevant to your topic, there’s a good chance a portion of the referenced works will be too. Do a quick scan of the titles and see what seems relevant, then search for the relevant ones in your university’s database.
Method 4 – Dissertation Scavenging
Similar to Method 3 above, you can leverage other students’ dissertations. All you have to do is skim through literature review chapters of existing dissertations related to your topic and you’ll find a gold mine of potential literature. Usually, your university will provide you with access to previous students’ dissertations, but you can also find a much larger selection in the following databases:
- Open Access Theses & Dissertations
- Stanford SearchWorks
Keep in mind that dissertations and theses are not as academically sound as published, peer-reviewed journal articles (because they’re written by students, not professionals), so be sure to check the credibility of any sources you find using this method. You can do this by assessing the citation count of any given article in Google Scholar. If you need help with assessing the credibility of any article, or with finding relevant research in general, you can chat with one of our Research Specialists .
Alright – with a good base of literature firmly under your belt, it’s time to move onto the next step.
Need a helping hand?
Step 2: Log, catalogue and synthesise
Once you’ve built a little treasure trove of articles, it’s time to get reading and start digesting the information – what does it all mean?
While I present steps one and two (hunting and digesting) as sequential, in reality, it’s more of a back-and-forth tango – you’ll read a little , then have an idea, spot a new citation, or a new potential variable, and then go back to searching for articles. This is perfectly natural – through the reading process, your thoughts will develop , new avenues might crop up, and directional adjustments might arise. This is, after all, one of the main purposes of the literature review process (i.e. to familiarise yourself with the current state of research in your field).
As you’re working through your treasure chest, it’s essential that you simultaneously start organising the information. There are three aspects to this:
- Logging reference information
- Building an organised catalogue
- Distilling and synthesising the information
I’ll discuss each of these below:
2.1 – Log the reference information
As you read each article, you should add it to your reference management software. I usually recommend Mendeley for this purpose (see the Mendeley 101 video below), but you can use whichever software you’re comfortable with. Most importantly, make sure you load EVERY article you read into your reference manager, even if it doesn’t seem very relevant at the time.
2.2 – Build an organised catalogue
In the beginning, you might feel confident that you can remember who said what, where, and what their main arguments were. Trust me, you won’t. If you do a thorough review of the relevant literature (as you must!), you’re going to read many, many articles, and it’s simply impossible to remember who said what, when, and in what context . Also, without the bird’s eye view that a catalogue provides, you’ll miss connections between various articles, and have no view of how the research developed over time. Simply put, it’s essential to build your own catalogue of the literature.
I would suggest using Excel to build your catalogue, as it allows you to run filters, colour code and sort – all very useful when your list grows large (which it will). How you lay your spreadsheet out is up to you, but I’d suggest you have the following columns (at minimum):
- Author, date, title – Start with three columns containing this core information. This will make it easy for you to search for titles with certain words, order research by date, or group by author.
- Categories or keywords – You can either create multiple columns, one for each category/theme and then tick the relevant categories, or you can have one column with keywords.
- Key arguments/points – Use this column to succinctly convey the essence of the article, the key arguments and implications thereof for your research.
- Context – Note the socioeconomic context in which the research was undertaken. For example, US-based, respondents aged 25-35, lower- income, etc. This will be useful for making an argument about gaps in the research.
- Methodology – Note which methodology was used and why. Also, note any issues you feel arise due to the methodology. Again, you can use this to make an argument about gaps in the research.
- Quotations – Note down any quoteworthy lines you feel might be useful later.
- Notes – Make notes about anything not already covered. For example, linkages to or disagreements with other theories, questions raised but unanswered, shortcomings or limitations, and so forth.
If you’d like, you can try out our free catalog template here (see screenshot below).
2.3 – Digest and synthesise
Most importantly, as you work through the literature and build your catalogue, you need to synthesise all the information in your own mind – how does it all fit together? Look for links between the various articles and try to develop a bigger picture view of the state of the research. Some important questions to ask yourself are:
- What answers does the existing research provide to my own research questions?
- Which points do the researchers agree (and disagree) on?
- How has the research developed over time?
- Where do the gaps in the current research lie?
To help you develop a big-picture view and synthesise all the information, you might find mind mapping software such as Freemind useful. Alternatively, if you’re a fan of physical note-taking, investing in a large whiteboard might work for you.
Step 3: Outline and write it up!
Once you’re satisfied that you have digested and distilled all the relevant literature in your mind, it’s time to put pen to paper (or rather, fingers to keyboard). There are two steps here – outlining and writing:
3.1 – Draw up your outline
Having spent so much time reading, it might be tempting to just start writing up without a clear structure in mind. However, it’s critically important to decide on your structure and develop a detailed outline before you write anything. Your literature review chapter needs to present a clear, logical and an easy to follow narrative – and that requires some planning. Don’t try to wing it!
Naturally, you won’t always follow the plan to the letter, but without a detailed outline, you’re more than likely going to end up with a disjointed pile of waffle , and then you’re going to spend a far greater amount of time re-writing, hacking and patching. The adage, “measure twice, cut once” is very suitable here.
In terms of structure, the first decision you’ll have to make is whether you’ll lay out your review thematically (into themes) or chronologically (by date/period). The right choice depends on your topic, research objectives and research questions, which we discuss in this article .
Once that’s decided, you need to draw up an outline of your entire chapter in bullet point format. Try to get as detailed as possible, so that you know exactly what you’ll cover where, how each section will connect to the next, and how your entire argument will develop throughout the chapter. Also, at this stage, it’s a good idea to allocate rough word count limits for each section, so that you can identify word count problems before you’ve spent weeks or months writing!
PS – check out our free literature review chapter template…
3.2 – Get writing
With a detailed outline at your side, it’s time to start writing up (finally!). At this stage, it’s common to feel a bit of writer’s block and find yourself procrastinating under the pressure of finally having to put something on paper. To help with this, remember that the objective of the first draft is not perfection – it’s simply to get your thoughts out of your head and onto paper, after which you can refine them. The structure might change a little, the word count allocations might shift and shuffle, and you might add or remove a section – that’s all okay. Don’t worry about all this on your first draft – just get your thoughts down on paper.
Let’s Recap
In this post, we’ve covered how to research and write up a high-quality literature review chapter. Let’s do a quick recap of the key takeaways:
- It is essential to understand the WHY of the literature review before you read or write anything. Make sure you understand the 4 core functions of the process.
- The first step is to hunt down the relevant literature . You can do this using Google Scholar, your university database, the snowballing technique and by reviewing other dissertations and theses.
- Next, you need to log all the articles in your reference manager , build your own catalogue of literature and synthesise all the research.
- Following that, you need to develop a detailed outline of your entire chapter – the more detail the better. Don’t start writing without a clear outline (on paper, not in your head!)
- Write up your first draft in rough form – don’t aim for perfection. Remember, done beats perfect.
- Refine your second draft and get a layman’s perspective on it . Then tighten it up and submit it to your supervisor.

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.

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.

How to Write a Literature Review
What is a literature review.
- What Is the Literature
- Writing the Review
A literature review is much more than an annotated bibliography or a list of separate reviews of articles and books. It is a critical, analytical summary and synthesis of the current knowledge of a topic. Thus it should compare and relate different theories, findings, etc, rather than just summarize them individually. In addition, it should have a particular focus or theme to organize the review. It does not have to be an exhaustive account of everything published on the topic, but it should discuss all the significant academic literature and other relevant sources important for that focus.
This is meant to be a general guide to writing a literature review: ways to structure one, what to include, how it supplements other research. For more specific help on writing a review, and especially for help on finding the literature to review, sign up for a Personal Research Session .
The specific organization of a literature review depends on the type and purpose of the review, as well as on the specific field or topic being reviewed. But in general, it is a relatively brief but thorough exploration of past and current work on a topic. Rather than a chronological listing of previous work, though, literature reviews are usually organized thematically, such as different theoretical approaches, methodologies, or specific issues or concepts involved in the topic. A thematic organization makes it much easier to examine contrasting perspectives, theoretical approaches, methodologies, findings, etc, and to analyze the strengths and weaknesses of, and point out any gaps in, previous research. And this is the heart of what a literature review is about. A literature review may offer new interpretations, theoretical approaches, or other ideas; if it is part of a research proposal or report it should demonstrate the relationship of the proposed or reported research to others' work; but whatever else it does, it must provide a critical overview of the current state of research efforts.
Literature reviews are common and very important in the sciences and social sciences. They are less common and have a less important role in the humanities, but they do have a place, especially stand-alone reviews.
Types of Literature Reviews
There are different types of literature reviews, and different purposes for writing a review, but the most common are:
- Stand-alone literature review articles . These provide an overview and analysis of the current state of research on a topic or question. The goal is to evaluate and compare previous research on a topic to provide an analysis of what is currently known, and also to reveal controversies, weaknesses, and gaps in current work, thus pointing to directions for future research. You can find examples published in any number of academic journals, but there is a series of Annual Reviews of *Subject* which are specifically devoted to literature review articles. Writing a stand-alone review is often an effective way to get a good handle on a topic and to develop ideas for your own research program. For example, contrasting theoretical approaches or conflicting interpretations of findings can be the basis of your research project: can you find evidence supporting one interpretation against another, or can you propose an alternative interpretation that overcomes their limitations?
- Part of a research proposal . This could be a proposal for a PhD dissertation, a senior thesis, or a class project. It could also be a submission for a grant. The literature review, by pointing out the current issues and questions concerning a topic, is a crucial part of demonstrating how your proposed research will contribute to the field, and thus of convincing your thesis committee to allow you to pursue the topic of your interest or a funding agency to pay for your research efforts.
- Part of a research report . When you finish your research and write your thesis or paper to present your findings, it should include a literature review to provide the context to which your work is a contribution. Your report, in addition to detailing the methods, results, etc. of your research, should show how your work relates to others' work.
A literature review for a research report is often a revision of the review for a research proposal, which can be a revision of a stand-alone review. Each revision should be a fairly extensive revision. With the increased knowledge of and experience in the topic as you proceed, your understanding of the topic will increase. Thus, you will be in a better position to analyze and critique the literature. In addition, your focus will change as you proceed in your research. Some areas of the literature you initially reviewed will be marginal or irrelevant for your eventual research, and you will need to explore other areas more thoroughly.
Examples of Literature Reviews
See the series of Annual Reviews of *Subject* which are specifically devoted to literature review articles to find many examples of stand-alone literature reviews in the biomedical, physical, and social sciences.
Research report articles vary in how they are organized, but a common general structure is to have sections such as:
- Abstract - Brief summary of the contents of the article
- Introduction - A explanation of the purpose of the study, a statement of the research question(s) the study intends to address
- Literature review - A critical assessment of the work done so far on this topic, to show how the current study relates to what has already been done
- Methods - How the study was carried out (e.g. instruments or equipment, procedures, methods to gather and analyze data)
- Results - What was found in the course of the study
- Discussion - What do the results mean
- Conclusion - State the conclusions and implications of the results, and discuss how it relates to the work reviewed in the literature review; also, point to directions for further work in the area
Here are some articles that illustrate variations on this theme. There is no need to read the entire articles (unless the contents interest you); just quickly browse through to see the sections, and see how each section is introduced and what is contained in them.
The Determinants of Undergraduate Grade Point Average: The Relative Importance of Family Background, High School Resources, and Peer Group Effects , in The Journal of Human Resources , v. 34 no. 2 (Spring 1999), p. 268-293.
This article has a standard breakdown of sections:
- Introduction
- Literature Review
- Some discussion sections
First Encounters of the Bureaucratic Kind: Early Freshman Experiences with a Campus Bureaucracy , in The Journal of Higher Education , v. 67 no. 6 (Nov-Dec 1996), p. 660-691.
This one does not have a section specifically labeled as a "literature review" or "review of the literature," but the first few sections cite a long list of other sources discussing previous research in the area before the authors present their own study they are reporting.

Follow the organizational structure you developed above, including the headings and subheadings you constructed.
Make certain that each section links logically to the one before and after.
Structure your sections by themes or subtopics, not by individual theorists or researchers.
- Tip: If you find that each paragraph begins with a researcher's name, it might indicate that, instead of evaluating and comparing the research literature from an analytical point of view, you have simply described what research has been done.
Prioritize analysis over description.
- For example, look at the following two passages and note that Student A merely describes the literature, whereas Student B takes a more analytical and evaluative approach by comparing and contrasting. You can also see that this evaluative approach is well signaled by linguistic markers indicating logical connections (words such as "however," "moreover") and phrases such as "substantiates the claim that," which indicate supporting evidence and Student B's ability to synthesize knowledge.
Student A: Smith (2000) concludes that personal privacy in their living quarters is the most important factor in nursing home residents' perception of their autonomy. He suggests that the physical environment in the more public spaces of the building did not have much impact on their perceptions. Neither the layout of the building nor the activities available seem to make much difference. Jones and Johnstone make the claim that the need to control one's environment is a fundamental need of life (2001), and suggest that the approach of most institutions, which is to provide total care, may be as bad as no care at all. If people have no choices or think that they have none, they become depressed.
Student B: After studying residents and staff from two intermediate care facilities in Calgary, Alberta, Smith (2000) came to the conclusion that except for the amount of personal privacy available to residents, the physical environment of these institutions had minimal if any effect on their perceptions of control (autonomy). However, French (1998) and Haroon (2000) found that availability of private areas is not the only aspect of the physical environment that determines residents' autonomy. Haroon interviewed 115 residents from 32 different nursing homes known to have different levels of autonomy (2000). It was found that physical structures, such as standardized furniture, heating that could not be individually regulated, and no possession of a house key for residents limited their feelings of independence. Moreover, Hope (2002), who interviewed 225 residents from various nursing homes, substantiates the claim that characteristics of the institutional environment such as the extent of resources in the facility, as well as its location, are features which residents have indicated as being of great importance to their independence.
- How to Integrate Critical Voice into Your Literature Review (Video)
- Look at the topic sentences of each paragraph. If you were to read only these sentences, would you find that your paper presented a clear position, logically developed, from beginning to end? The topic sentences of each paragraph should indicate the main points of your literature review.
- Make an outline of each section of the paper and decide whether you need to add information, to delete irrelevant information, or to re-structure sections.
- Read your work out loud. That way you will be better able to identify where you need punctuation marks to signal pauses or divisions within sentences, where you have made grammatical errors, or where your sentences are unclear.
- Since the purpose of a literature review is to demonstrate that the writer is familiar with the important professional literature on the chosen subject, check to make certain that you have covered all of the important, up-to-date, and pertinent texts. In the sciences and some of the social sciences it is important that your literature be quite recent; this is not so important in the humanities.
- Make certain that all of the citations and references are correct and that you are referencing in the appropriate style for your discipline. If you are uncertain which style to use, ask your professor.
- Check to make sure that you have not plagiarized either by failing to cite a source of information, or by using words quoted directly from a source. (Usually if you take three or more words directly from another source, you should put those words within quotation marks, and cite the page.)
- Text should be written in a clear and concise academic style; it should not be descriptive in nature or use the language of everyday speech.
- There should be no grammatical or spelling errors.
- Sentences should flow smoothly and logically.

Frequently asked questions
What is the purpose of a literature review.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize 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.
Frequently asked questions: Academic writing
You may have seen both “appendices” or “appendixes” as pluralizations of “ appendix .” Either spelling can be used, but “appendices” is more common (including in APA Style ). Consistency is key here: make sure you use the same spelling throughout your paper.
The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.
In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.
A lab report is usually shorter than a research paper.
The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:
- Title: expresses the topic of your study
- Abstract: summarizes your research aims, methods, results, and conclusions
- Introduction: establishes the context needed to understand the topic
- Method: describes the materials and procedures used in the experiment
- Results: reports all descriptive and inferential statistical analyses
- Discussion: interprets and evaluates results and identifies limitations
- Conclusion: sums up the main findings of your experiment
- References: list of all sources cited using a specific style (e.g. APA)
- Appendices: contains lengthy materials, procedures, tables or figures
A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.
The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .
If you’ve gone over the word limit set for your assignment, shorten your sentences and cut repetition and redundancy during the editing process. If you use a lot of long quotes , consider shortening them to just the essentials.
If you need to remove a lot of words, you may have to cut certain passages. Remember that everything in the text should be there to support your argument; look for any information that’s not essential to your point and remove it.
Revising, proofreading, and editing are different stages of the writing process .
- Revising is making structural and logical changes to your text—reformulating arguments and reordering information.
- Editing refers to making more local changes to things like sentence structure and phrasing to make sure your meaning is conveyed clearly and concisely.
- Proofreading involves looking at the text closely, line by line, to spot any typos and issues with consistency and correct them.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
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 thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
Avoid citing sources in your abstract . There are two reasons for this:
- The abstract should focus on your original research, not on the work of others.
- The abstract should be self-contained and fully understandable without reference to other sources.
There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.
An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:
- To help potential readers determine the relevance of your paper for their own research.
- To communicate your key findings to those who don’t have time to read the whole paper.
Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.
In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .
Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.
Whether you’re publishing a blog, submitting a research paper , or even just writing an important email, there are a few techniques you can use to make sure it’s error-free:
- Take a break : Set your work aside for at least a few hours so that you can look at it with fresh eyes.
- Proofread a printout : Staring at a screen for too long can cause fatigue – sit down with a pen and paper to check the final version.
- Use digital shortcuts : Take note of any recurring mistakes (for example, misspelling a particular word, switching between US and UK English , or inconsistently capitalizing a term), and use Find and Replace to fix it throughout the document.
If you want to be confident that an important text is error-free, it might be worth choosing a professional proofreading service instead.
Editing and proofreading are different steps in the process of revising a text.
Editing comes first, and can involve major changes to content, structure and language. The first stages of editing are often done by authors themselves, while a professional editor makes the final improvements to grammar and style (for example, by improving sentence structure and word choice ).
Proofreading is the final stage of checking a text before it is published or shared. It focuses on correcting minor errors and inconsistencies (for example, in punctuation and capitalization ). Proofreaders often also check for formatting issues, especially in print publishing.
The cost of proofreading depends on the type and length of text, the turnaround time, and the level of services required. Most proofreading companies charge per word or page, while freelancers sometimes charge an hourly rate.
For proofreading alone, which involves only basic corrections of typos and formatting mistakes, you might pay as little as $0.01 per word, but in many cases, your text will also require some level of editing , which costs slightly more.
It’s often possible to purchase combined proofreading and editing services and calculate the price in advance based on your requirements.
There are many different routes to becoming a professional proofreader or editor. The necessary qualifications depend on the field – to be an academic or scientific proofreader, for example, you will need at least a university degree in a relevant subject.
For most proofreading jobs, experience and demonstrated skills are more important than specific qualifications. Often your skills will be tested as part of the application process.
To learn practical proofreading skills, you can choose to take a course with a professional organization such as the Society for Editors and Proofreaders . Alternatively, you can apply to companies that offer specialized on-the-job training programmes, such as the Scribbr Academy .

To help you frame and write your literature review, think about these five 'c's (Callahan, 2014). Cite the material you have referred to and used to help you define the research problem that you will study. Compare the various arguments, theories, methods, and findings expressed in the literature.
Critique the literature. Describe which arguments you find more persuasive and explain why. Explain which approaches, findings, and methods seem most reliable, valid, appropriate, and/or most popular and why. Pay attention to the verbs you use to describe what previous researchers have stated (e.g., asserts, demonstrates, argues, clarifies, etc.).
To introduce you to this world of academic writing, in this chapter I suggest that you should focus on five hierarchical characteristics of good writing, or the "5 Cs" of good academic writing, which include Clarity, Cogency, Conventionality, Completeness, and Concision.

When writing a literature review it is important to start with a brief introduction, followed by the text broken up into subsections and conclude with a summary to bring everything together. A summary table including title, author, publication date and key findings is a useful feature to present in your review (see Table 1 for an example).
A literature review is valuable because of the insights you provide. Evaluate critically: Be sure to remain as objective as possible. Structure your paragraphs: Keep each paragraph to one main theme, and include transitional sentences to make each paragraph flow neatly to the next.
The 5 C's of writing a literature review are as follows: Context: Provide the context for your literature review by explaining the background and significance of the research question or topic you are exploring. This helps readers understand why your review is important and how it fits into the broader field of study.

A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period. A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis.

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components - an introduction, a body and a conclusion. Let's take a closer look at each of these. 1: The Introduction Section
As mentioned above, writing your literature review is a process, which I'll break down into three steps: Finding the most suitable literature. Understanding, distilling and organising the literature. Planning and writing up your literature review chapter. Importantly, you must complete steps one and two before you start writing up your chapter.
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.
Your report, in addition to detailing the methods, results, etc. of your research, should show how your work relates to others' work. A literature review for a research report is often a revision of the review for a research proposal, which can be a revision of a stand-alone review. Each revision should be a fairly extensive revision.
Ten Simple Rules for Writing a Literature Review. Rule 1: Define a Topic and Audience. Rule 2: Search and Re-search the Literature. Rule 3: Take Notes While Reading. Rule 4: Choose the Type of Review You Wish to Write. Rule 5: Keep the Review Focused, but Make It of Broad Interest. Rule 6: Be Critical and Consistent.
Seven Steps to Writing a Literature Review - Write a Literature Review - Guides at University of Guelph 1. Narrow your topic and select papers accordingly Consider your specific area of study. Think about what interests you and what interests other researchers in your field.
4 Unit 4.5: Ethical Standards in Writing Literature Review Defining Plagiarism One of the most common yet serious errors when writing a literature review, or a research paper in general, is plagiarism.
Step 5: Rate the Book (Optional) After writing a book review, you may want to include a rating. Including a star-rating provides further insight into the quality of the book, to your readers. Book reviews with star-ratings can be moreeffective, compared to those which don't. Though, this is entirely optional.
There are several reasons to conduct a literature review at the beginning of a research project: To familiarize 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.
