Exploring the literature review

Literature review model: 6 steps.

Adapted from The Literature Review , Machi & McEvoy (2009, p. 13).

Your Literature Review

Step 2: search, boolean search strategies, search limiters, ★ ebsco & google drive.

1. Select a Topic

"All research begins with curiosity" (Machi & McEvoy, 2009, p. 14)

Selection of a topic, and fully defined research interest and question, is supervised (and approved) by your professor. Tips for crafting your topic include:

Be specific. Take time to define your interest.
Topic Focus. Fully describe and sufficiently narrow the focus for research.
Academic Discipline. Learn more about your area of research & refine the scope.
Avoid Bias. Be aware of bias that you (as a researcher) may have.
Document your research. Use Google Docs to track your research process.
Research apps. Consider using Evernote or Zotero to track your research.

Consider Purpose

What will your topic and research address?

In The Literature Review: A Step-by-Step Guide for Students , Ridley presents that literature reviews serve several purposes (2008, p. 16-17). Included are the following points:

Historical background for the research;
Overview of current field provided by "contemporary debates, issues, and questions;"
Theories and concepts related to your research;
Introduce "relevant terminology" - or academic language - being used it the field;
Connect to existing research - does your work "extend or challenge [this] or address a gap;"
Provide "supporting evidence for a practical problem or issue" that your research addresses.

★ Schedule a research appointment

At this point in your literature review, take time to meet with a librarian. Why? Understanding the subject terminology used in databases can be challenging. Archer Librarians can help you structure a search, preparing you for step two. How? Contact a librarian directly or use the online form to schedule an appointment. Details are provided in the adjacent Schedule an Appointment box.

2. Search the Literature

Collect & Select Data: Preview, select, and organize

AU Library is your go-to resource for this step in your literature review process. The literature search will include books and ebooks, scholarly and practitioner journals, theses and dissertations, and indexes. You may also choose to include web sites, blogs, open access resources, and newspapers. This library guide provides access to resources needed to complete a literature review.

Books & eBooks: Archer Library & OhioLINK

Databases: scholarly & practitioner journals.

Review the Library Databases tab on this library guide, it provides links to recommended databases for Education & Psychology, Business, and General & Social Sciences.

Expand your journal search; a complete listing of available AU Library and OhioLINK databases is available on the Databases A to Z list . Search the database by subject, type, name, or do use the search box for a general title search. The A to Z list also includes open access resources and select internet sites.

Databases: Theses & Dissertations

Review the Library Databases tab on this guide, it includes Theses & Dissertation resources. AU library also has AU student authored theses and dissertations available in print, search the library catalog for these titles.

Did you know? If you are looking for particular chapters within a dissertation that is not fully available online, it is possible to submit an ILL article request . Do this instead of requesting the entire dissertation.

Newspapers: Databases & Internet

Consider current literature in your academic field. AU Library's database collection includes The Chronicle of Higher Education and The Wall Street Journal . The Internet Resources tab in this guide provides links to newspapers and online journals such as Inside Higher Ed , COABE Journal , and Education Week .

Search Strategies & Boolean Operators

There are three basic boolean operators: AND, OR, and NOT.

Used with your search terms, boolean operators will either expand or limit results. What purpose do they serve? They help to define the relationship between your search terms. For example, using the operator AND will combine the terms expanding the search. When searching some databases, and Google, the operator AND may be implied.

Overview of boolean terms

About the example: Boolean searches were conducted on November 4, 2019; result numbers may vary at a later date. No additional database limiters were set to further narrow search returns.

Database Search Limiters

Database strategies for targeted search results.

Most databases include limiters, or additional parameters, you may use to strategically focus search results. EBSCO databases, such as Education Research Complete & Academic Search Complete provide options to:

Limit results to full text;
Limit results to scholarly journals, and reference available;
Select results source type to journals, magazines, conference papers, reviews, and newspapers
Publication date

Keep in mind that these tools are defined as limiters for a reason; adding them to a search will limit the number of results returned. This can be a double-edged sword. How?

If limiting results to full-text only, you may miss an important piece of research that could change the direction of your research. Interlibrary loan is available to students, free of charge. Request articles that are not available in full-text; they will be sent to you via email.
If narrowing publication date, you may eliminate significant historical - or recent - research conducted on your topic.
Limiting resource type to a specific type of material may cause bias in the research results.

Use limiters with care. When starting a search, consider opting out of limiters until the initial literature screening is complete. The second or third time through your research may be the ideal time to focus on specific time periods or material (scholarly vs newspaper).

★ Truncating Search Terms

Expanding your search term at the root.

Truncating is often referred to as 'wildcard' searching. Databases may have their own specific wildcard elements however, the most commonly used are the asterisk (*) or question mark (?). When used within your search. they will expand returned results.

Asterisk (*) Wildcard

Using the asterisk wildcard will return varied spellings of the truncated word. In the following example, the search term education was truncated after the letter "t."

Defining Literature Review

What is a literature review.

A definition from the Online Dictionary for Library and Information Sciences .

A literature review is "a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works" (Reitz, 2014).

A systemic review is "a literature review focused on a specific research question, which uses explicit methods to minimize bias in the identification, appraisal, selection, and synthesis of all the high-quality evidence pertinent to the question" (Reitz, 2014).

Chapter 9. Reviewing the Literature

What is a “literature review”.

No researcher ever comes up with a research question that is wholly novel. Someone, somewhere, has asked the same thing. Academic research is part of a larger community of researchers, and it is your responsibility, as a member of this community, to acknowledge others who have asked similar questions and to put your particular research into this greater context. It is not simply a convention or custom to begin your study with a review of previous literature (the “ lit review ”) but an important responsibility you owe the scholarly community.

Too often, new researchers pursue a topic to study and then write something like, “No one has ever studied this before” or “This area is underresearched.” It may be that no one has studied this particular group or setting, but it is highly unlikely no one has studied the foundational phenomenon of interest. And that comment about an area being underresearched? Be careful. The statement may simply signal to others that you haven’t done your homework. Rubin ( 2021 ) refers to this as “free soloing,” and it is not appreciated in academic work:

The truth of the matter is, academics don’t really like when people free solo. It’s really bad form to omit talking about the other people who are doing or have done research in your area. Partly, I mean we need to cite their work, but I also mean we need to respond to it—agree or disagree, clarify for extend. It’s also really bad form to talk about your research in a way that does not make it understandable to other academics.…You have to explain to your readers what your story is really about in terms they care about . This means using certain terminology, referencing debates in the literature, and citing relevant works—that is, in connecting your work to something else. ( 51–52 )

A literature review is a comprehensive summary of previous research on a topic. It includes both articles and books—and in some cases reports—relevant to a particular area of research. Ideally, one’s research question follows from the reading of what has already been produced. For example, you are interested in studying sports injuries related to female gymnasts. You read everything you can find on sports injuries related to female gymnasts, and you begin to get a sense of what questions remain open. You find that there is a lot of research on how coaches manage sports injuries and much about cultures of silence around treating injuries, but you don’t know what the gymnasts themselves are thinking about these issues. You look specifically for studies about this and find several, which then pushes you to narrow the question further. Your literature review then provides the road map of how you came to your very specific question, and it puts your study in the context of studies of sports injuries. What you eventually find can “speak to” all the related questions as well as your particular one.

In practice, the process is often a bit messier. Many researchers, and not simply those starting out, begin with a particular question and have a clear idea of who they want to study and where they want to conduct their study but don’t really know much about other studies at all. Although backward, we need to recognize this is pretty common. Telling students to “find literature” after the fact can seem like a purposeless task or just another hurdle for completing a thesis or dissertation. It is not! Even if you were not motivated by the literature in the first place, acknowledging similar studies and connecting your own research to those studies are important parts of building knowledge. Acknowledgment of past research is a responsibility you owe the discipline to which you belong.

Literature reviews can also signal theoretical approaches and particular concepts that you will incorporate into your own study. For example, let us say you are doing a study of how people find their first jobs after college, and you want to use the concept of social capital . There are competing definitions of social capital out there (e.g., Bourdieu vs. Burt vs. Putnam). Bourdieu’s notion is of one form of capital, or durable asset, of a “network of more or less institutionalized relationships of mutual acquaintance or recognition” ( 1984:248 ). Burt emphasizes the “brokerage opportunities” in a social network as social capital ( 1997:355 ). Putnam’s social capital is all about “facilitating coordination and cooperation for mutual benefit” ( 2001:67 ). Your literature review can adjudicate among these three approaches, or it can simply refer to the one that is animating your own research. If you include Bourdieu in your literature review, readers will know “what kind” of social capital you are talking about as well as what kind of social scientist you yourself are. They will likely understand that you are interested more in how some people are advantaged by their social capital relative to others rather than being interested in the mechanics of how social networks operate.

The literature review thus does two important things for you: firstly, it allows you to acknowledge previous research in your area of interest, thereby situating you within a discipline or body of scholars, and, secondly, it demonstrates that you know what you are talking about. If you present the findings of your research study without including a literature review, it can be like singing into the wind. It sounds nice, but no one really hears it, or if they do catch snippets, they don’t know where it is coming from.

Examples of Literature Reviews

To help you get a grasp of what a good literature review looks like and how it can advance your study, let’s take a look at a few examples.

Reader-Friendly Example: The Power of Peers

The first is by Janice McCabe ( 2016 ) and is from an article on peer networks in the journal Contexts . Contexts presents articles in a relatively reader-friendly format, with the goal of reaching a large audience for interesting sociological research. Read this example carefully and note how easily McCabe is able to convey the relevance of her own work by situating it in the context of previous studies:

Scholars who study education have long acknowledged the importance of peers for students’ well-being and academic achievement. For example, in 1961, James Coleman argued that peer culture within high schools shapes students’ social and academic aspirations and successes. More recently, Judith Rich Harris has drawn on research in a range of areas—from sociological studies of preschool children to primatologists’ studies of chimpanzees and criminologists’ studies of neighborhoods—to argue that peers matter much more than parents in how children “turn out.” Researchers have explored students’ social lives in rich detail, as in Murray Milner’s book about high school students, Freaks, Geeks, and Cool Kids , and Elizabeth Armstrong and Laura Hamilton’s look at college students, Paying for the Party . These works consistently show that peers play a very important role in most students’ lives. They tend, however, to prioritize social over academic influence and to use a fuzzy conception of peers rather than focusing directly on friends—the relationships that should matter most for student success. Social scientists have also studied the power of peers through network analysis, which is based on uncovering the web of connections between people. Network analysis involves visually mapping networks and mathematically comparing their structures (such as the density of ties) and the positions of individuals within them (such as how central a given person is within the network). As Nicholas Christakis and James Fowler point out in their book Connected , network structure influences a range of outcomes, including health, happiness, wealth, weight, and emotions. Given that sociologists have long considered network explanations for social phenomena, it’s surprising that we know little about how college students’ friends impact their experiences. In line with this network tradition, I focus on the structure of friendship networks, constructing network maps so that the differences we see across participants are due to the underlying structure, including each participant’s centrality in their friendship group and the density of ties among their friends. ( 23 )

What did you notice? In her very second sentence, McCabe uses “for example” to introduce a study by Coleman, thereby indicating that she is not going to tell you every single study in this area but is going to tell you that (1) there is a lot of research in this area, (2) it has been going on since at least 1961, and (3) it is still relevant (i.e., recent studies are still being done now). She ends her first paragraph by summarizing the body of literature in this area (after giving you a few examples) and then telling you what may have been (so far) left out of this research. In the second paragraph, she shifts to a separate interesting focus that is related to the first but is also quite distinct. Lit reviews very often include two (or three) distinct strands of literature, the combination of which nicely backgrounds this particular study . In the case of our female gymnast study (above), those two strands might be (1) cultures of silence around sports injuries and (2) the importance of coaches. McCabe concludes her short and sweet literature review with one sentence explaining how she is drawing from both strands of the literature she has succinctly presented for her particular study. This example should show you that literature reviews can be readable, helpful, and powerful additions to your final presentation.

Authoritative Academic Journal Example: Working Class Students’ College Expectations

The second example is more typical of academic journal writing. It is an article published in the British Journal of Sociology of Education by Wolfgang Lehmann ( 2009 ):

Although this increase in post-secondary enrolment and the push for university is evident across gender, race, ethnicity, and social class categories, access to university in Canada continues to be significantly constrained for those from lower socio-economic backgrounds (Finnie, Lascelles, and Sweetman 2005). Rising tuition fees coupled with an overestimation of the cost and an underestimation of the benefits of higher education has put university out of reach for many young people from low-income families (Usher 2005). Financial constraints aside, empirical studies in Canada have shown that the most important predictor of university access is parental educational attainment. Having at least one parent with a university degree significantly increases the likelihood of a young person to attend academic-track courses in high school, have high educational and career aspirations, and ultimately attend university (Andres et al. 1999, 2000; Lehmann 2007a). Drawing on Bourdieu’s various writing on habitus and class-based dispositions (see, for example, Bourdieu 1977, 1990), Hodkinson and Sparkes (1997) explain career decisions as neither determined nor completely rational. Instead, they are based on personal experiences (e.g., through employment or other exposure to occupations) and advice from others. Furthermore, they argue that we have to understand these decisions as pragmatic, rather than rational. They are pragmatic in that they are based on incomplete and filtered information, because of the social context in which the information is obtained and processed. New experiences and information can, however, also be allowed into one’s world, where they gradually or radically transform habitus, which in turn creates the possibility for the formation of new and different dispositions. Encountering a supportive teacher in elementary or secondary school, having ambitious friends, or chance encounters can spark such transformations. Transformations can be confirming or contradictory, they can be evolutionary or dislocating. Working-class students who enter university most certainly encounter such potentially transformative situations. Granfield (1991) has shown how initially dislocating feelings of inadequacy and inferiority of working-class students at an elite US law school were eventually replaced by an evolutionary transformation, in which the students came to dress, speak and act more like their middle-class and upper-class peers. In contrast, Lehmann (2007b) showed how persistent habitus dislocation led working-class university students to drop out of university. Foskett and Hemsley-Brown (1999) argue that young people’s perceptions of careers are a complex mix of their own experiences, images conveyed through adults, and derived images conveyed by the media. Media images of careers, perhaps, are even more important for working-class youth with high ambitions as they offer (generally distorted) windows into a world of professional employment to which they have few other sources of access. It has also been argued that working-class youth who do continue to university still face unique, class-specific challenges, evident in higher levels of uncertainty (Baxter and Britton 2001; Lehmann 2004, 2007a; Quinn 2004), their higher education choices (Ball et al. 2002; Brooks 2003; Reay et al. 2001) and fears of inadequacy because of their cultural outsider status (Aries and Seider 2005; Granfield 1991). Although the number of working-class university students in Canada has slowly increased, that of middle-class students at university has risen far more steeply (Knighton and Mizra 2002). These different enrolment trajectories have actually widened the participation gap, which in tum explains our continued concerns with the potential outsider status Indeed, in a study comparing first-generation working-class and traditional students who left university without graduating, Lehmann (2007b) found that first-generation working-class students were more likely to leave university very early in some cases within the first two months of enrollment. They were also more likely to leave university despite solid academic performance. Not “fitting in,” not “feeling university,” and not being able to “relate to these people” were key reasons for eventually withdrawing from university. From the preceding review of the literature, a number of key research questions arise: How do working-class university students frame their decision to attend university? How do they defy the considerable odds documented in the literature to attend university? What are the sources of information and various images that create dispositions to study at university? What role does their social-class background- or habitus play in their transition dispositions and how does this translate into expectations for university? ( 139 )

What did you notice here? How is this different from (and similar to) the first example? Note that rather than provide you with one or two illustrative examples of similar types of research, Lehmann provides abundant source citations throughout. He includes theory and concepts too. Like McCabe, Lehmann is weaving through multiple literature strands: the class gap in higher education participation in Canada, class-based dispositions, and obstacles facing working-class college students. Note how he concludes the literature review by placing his research questions in context.

Find other articles of interest and read their literature reviews carefully. I’ve included two more for you at the end of this chapter . As you learned how to diagram a sentence in elementary school (hopefully!), try diagramming the literature reviews. What are the “different strands” of research being discussed? How does the author connect these strands to their own research questions? Where is theory in the lit review, and how is it incorporated (e.g., Is it a separate strand of its own or is it inextricably linked with previous research in this area)?

One model of how to structure your literature review can be found in table 9.1. More tips, hints, and practices will be discussed later in the chapter.

Table 9.1. Model of Literature Review, Adopted from Calarco (2020:166)

Embracing Theory

A good research study will, in some form or another, use theory. Depending on your particular study (and possibly the preferences of the members of your committee), theory may be built into your literature review. Or it may form its own section in your research proposal/design (e.g., “literature review” followed by “theoretical framework”). In my own experience, I see a lot of graduate students grappling with the requirement to “include theory” in their research proposals. Things get a little squiggly here because there are different ways of incorporating theory into a study (Are you testing a theory? Are you generating a theory?), and based on these differences, your literature review proper may include works that describe, explain, and otherwise set forth theories, concepts, or frameworks you are interested in, or it may not do this at all. Sometimes a literature review sets forth what we know about a particular group or culture totally independent of what kinds of theoretical framework or particular concepts you want to explore. Indeed, the big point of your study might be to bring together a body of work with a theory that has never been applied to it previously. All this is to say that there is no one correct way to approach the use of theory and the writing about theory in your research proposal.

Students are often scared of embracing theory because they do not exactly understand what it is. Sometimes, it seems like an arbitrary requirement. You’re interested in a topic; maybe you’ve even done some research in the area and you have findings you want to report. And then a committee member reads over what you have and asks, “So what?” This question is a good clue that you are missing theory, the part that connects what you have done to what other researchers have done and are doing. You might stumble upon this rather accidentally and not know you are embracing theory, as in a case where you seek to replicate a prior study under new circumstances and end up finding that a particular correlation between behaviors only happens when mediated by something else. There’s theory in there, if you can pull it out and articulate it. Or it might be that you are motivated to do more research on racial microaggressions because you want to document their frequency in a particular setting, taking for granted the kind of critical race theoretical framework that has done the hard work of defining and conceptualizing “microaggressions” in the first place. In that case, your literature review could be a review of Critical Race Theory, specifically related to this one important concept. That’s the way to bring your study into a broader conversation while also acknowledging (and honoring) the hard work that has preceded you.

Rubin ( 2021 ) classifies ways of incorporating theory into case study research into four categories, each of which might be discussed somewhat differently in a literature review or theoretical framework section. The first, the least theoretical, is where you set out to study a “configurative idiographic case” ( 70 ) This is where you set out to describe a particular case, leaving yourself pretty much open to whatever you find. You are not expecting anything based on previous literature. This is actually pretty weak as far as research design goes, but it is probably the default for novice researchers. Your committee members should probably help you situate this in previous literature in some way or another. If they cannot, and it really does appear you are looking at something fairly new that no one else has bothered to research before, and you really are completely open to discovery, you might try using a Grounded Theory approach, which is a methodological approach that foregrounds the generation of theory. In that case, your “theory” section can be a discussion of “Grounded Theory” methodology (confusing, yes, but if you take some time to ponder, you will see how this works). You will still need a literature review, though. Ideally one that describes other studies that have ever looked at anything remotely like what you are looking at—parallel cases that have been researched.

The second approach is the “disciplined configurative case,” in which theory is applied to explain a particular case or topic. You are not trying to test the theory but rather assuming the theory is correct, as in the case of exploring microaggressions in a particular setting. In this case, you really do need to have a separate theory section in addition to the literature review, one in which you clearly define the theoretical framework, including any of its important concepts. You can use this section to discuss how other researchers have used the concepts and note any discrepancies in definitions or operationalization of those concepts. This way you will be sure to design your study so that it speaks to and with other researchers. If everyone who is writing about microaggressions has a different definition of them, it is hard for others to compare findings or make any judgments about their prevalence (or any number of other important characteristics). Your literature review section may then stand alone and describe previous research in the particular area or setting, irrespective of the kinds of theory underlying those studies.

The third approach is “heuristic,” one in which you seek to identify new variables, hypotheses, mechanisms, or paths not yet explained by a theory or theoretical framework. In a way, you are generating new theory, but it is probably more accurate to say that you are extending or deepening preexisting theory. In this case, having a single literature review that is focused on the theory and the ways the theory has been applied and understood (with all its various mechanisms and pathways) is probably your best option. The focus of the literature reviewed is less on the case and more on the theory you are seeking to extend.

The final approach is “theory testing,” which is much rarer in qualitative studies than in quantitative, where this is the default approach. Theory-testing cases are those where a particular case is used to see if an existing theory is accurate or accurate under particular circumstances. As with the heuristic approach, your literature review will probably draw heavily on previous uses of the theory, but you may end up having a special section specifically about cases very close to your own . In other words, the more your study approaches theory testing, the more likely there is to be a set of similar studies to draw on or even one important key study that you are setting your own study up in parallel to in order to find out if the theory generated there operates here.

If we wanted to get very technical, it might be useful to distinguish theoretical frameworks properly from conceptual frameworks. The latter are a bit looser and, given the nature of qualitative research, often fit exploratory studies. Theoretical frameworks rely on specific theories and are essential for theory-testing studies. Conceptual frameworks can pull in specific concepts or ideas that may or may not be linked to particular theories. Think about it this way: A theory is a story of how the world works. Concepts don’t presume to explain the whole world but instead are ways to approach phenomena to help make sense of them. Microaggressions are concepts that are linked to Critical Race Theory. One could contextualize one’s study within Critical Race Theory and then draw various concepts, such as that of microaggressions from the overall theoretical framework. Or one could bracket out the master theory or framework and employ the concept of microaggression more opportunistically as a phenomenon of interest. If you are unsure of what theory you are using, you might want to frame a more practical conceptual framework in your review of the literature.

Helpful Tips

How to maintain good notes for what your read.

Over the years, I have developed various ways of organizing notes on what I read. At first, I used a single sheet of full-size paper with a preprinted list of questions and points clearly addressed on the front side, leaving the second side for more reflective comments and free-form musings about what I read, why it mattered, and how it might be useful for my research. Later, I developed a system in which I use a single 4″ × 6″ note card for each book I read. I try only to use the front side (and write very small), leaving the back for comments that are about not just this reading but things to do or examine or consider based on the reading. These notes often mean nothing to anyone else picking up the card, but they make sense to me. I encourage you to find an organizing system that works for you. Then when you set out to compose a literature review, instead of staring at five to ten books or a dozen articles, you will have ten neatly printed pages or notecards or files that have distilled what is important to know about your reading.

It is also a good idea to store this data digitally, perhaps through a reference manager. I use RefWorks, but I also recommend EndNote or any other system that allows you to search institutional databases. Your campus library will probably provide access to one of these or another system. Most systems will allow you to export references from another manager if and when you decide to move to another system. Reference managers allow you to sort through all your literature by descriptor, author, year, and so on. Even so, I personally like to have the ability to manually sort through my index cards, recategorizing things I have read as I go. I use RefWorks to keep a record of what I have read, with proper citations, so I can create bibliographies more easily, and I do add in a few “notes” there, but the bulk of my notes are kept in longhand.

What kinds of information should you include from your reading? Here are some bulleted suggestions from Calarco ( 2020:113–114 ), with my own emendations:

Citation . If you are using a reference manager, you can import the citation and then, when you are ready to create a bibliography, you can use a provided menu of citation styles, which saves a lot of time. If you’ve originally formatted in Chicago Style but the journal you are writing for wants APA style, you can change your entire bibliography in less than a minute. When using a notecard for a book, I include author, title, date as well as the library call number (since most of what I read I pull from the library). This is something RefWorks is not able to do, and it helps when I categorize.

I begin each notecard with an “intro” section, where I record the aims, goals, and general point of the book/article as explained in the introductory sections (which might be the preface, the acknowledgments, or the first two chapters). I then draw a bold line underneath this part of the notecard. Everything after that should be chapter specific. Included in this intro section are things such as the following, recommended by Calarco ( 2020 ):

Key background . “Two to three short bullet points identifying the theory/prior research on which the authors are building and defining key terms.”
Data/methods . “One or two short bullet points with information about the source of the data and the method of analysis, with a note if this is a novel or particularly effective example of that method.” I use [M] to signal methodology on my notecard, which might read, “[M] Int[erview]s (n-35), B[lack]/W[hite] voters” (I need shorthand to fit on my notecard!).
Research question . “Stated as briefly as possible.” I always provide page numbers so I can go back and see exactly how this was stated (sometimes, in qualitative research, there are multiple research questions, and they cannot be stated simply).
Argument/contributions . “Two to three short bullet points briefly describing the authors’ answer to the central research question and its implication for research, theory, and practice.” I use [ARG] for argument to signify the argument, and I make sure this is prominently visible on my notecard. I also provide page numbers here.

For me, all of this fits in the “intro” section, which, if this is a theoretically rich, methodologically sound book, might take up a third or even half of the front page of my notecard. Beneath the bold underline, I report specific findings or particulars of the book as they emerge chapter by chapter. Calarco’s ( 2020 ) next step is the following:

Key findings . “Three to four short bullet points identifying key patterns in the data that support the authors’ argument.”

All that remains is writing down thoughts that occur upon finishing the article/book. I use the back of the notecard for these kinds of notes. Often, they reach out to other things I have read (e.g., “Robinson reminds me of Crusoe here in that both are looking at the effects of social isolation, but I think Robinson makes a stronger argument”). Calarco ( 2020 ) concludes similarly with the following:

Unanswered questions . “Two to three short bullet points that identify key limitations of the research and/or questions the research did not answer that could be answered in future research.”

As I mentioned, when I first began taking notes like this, I preprinted pages with prompts for “research question,” “argument,” and so on. This was a great way to remind myself to look for these things in particular. You can do the same, adding whatever preprinted sections make sense to you, given what you are studying and the important aspects of your discipline. The other nice thing about the preprinted forms is that it keeps your writing to a minimum—you cannot write more than the allotted space, even if you might want to, preventing your notes from spiraling out of control. This can be helpful when we are new to a subject and everything seems worth recording!

After years of discipline, I have finally settled on my notecard approach. I have thousands of notecards, organized in several index card filing boxes stacked in my office. On the top right of each card is a note of the month/day I finished reading the item. I can remind myself what I read in the summer of 2010 if the need or desire ever arose to do so…those invaluable notecards are like a memento of what my brain has been up to!

Where to Start Looking for Literature

Your university library should provide access to one of several searchable databases for academic books and articles. My own preference is JSTOR, a service of ITHAKA, a not-for-profit organization that works to advance and preserve knowledge and to improve teaching and learning through the use of digital technologies. JSTOR allows you to search by several keywords and to narrow your search by type of material (articles or books). For many disciplines, the “literature” of the literature review is expected to be peer-reviewed “articles,” but some disciplines will also value books and book chapters. JSTOR is particularly useful for article searching. You can submit several keywords and see what is returned, and you can also narrow your search by a particular journal or discipline. If your discipline has one or two key journals (e.g., the American Journal of Sociology and the American Sociological Review are key for sociology), you might want to go directly to those journals’ websites and search for your topic area. There is an art to when to cast your net widely and when to refine your search, and you may have to tack back and forth to ensure that you are getting all that is relevant but not getting bogged down in all studies that might have some marginal relevance.

Some articles will carry more weight than others, and you can use applications like Google Scholar to see which articles have made and are continuing to make larger impacts on your discipline. Find these articles and read them carefully; use their literature review and the sources cited in those articles to make sure you are capturing what is relevant. This is actually a really good way of finding relevant books—only the most impactful will make it into the citations of journals. Over time, you will notice that a handful of articles (or books) are cited so often that when you see, say, Armstrong and Hamilton ( 2015 ), you know exactly what book this is without looking at the full cite. This is when you know you are in the conversation.

You might also approach a professor whose work is broadly in the area of your interest and ask them to recommend one or two “important” foundational articles or books. You can then use the references cited in those recommendations to build up your literature. Just be careful: some older professors’ knowledge of the literature (and I reluctantly add myself here) may be a bit outdated! It is best that the article or book whose references and sources you use to build your body of literature be relatively current.

Keep a List of Your Keywords

When using searchable databases, it is a good idea to keep a list of all the keywords you use as you go along so that (1) you do not needlessly duplicate your efforts and (2) you can more easily adjust your search as you get a better sense of what you are looking for. I suggest you keep a separate file or even a small notebook for this and you date your search efforts.

Here’s an example:

Table 9.2. Keep a List of Your Keywords

Think Laterally

How to find the various strands of literature to combine? Don’t get stuck on finding the exact same research topic you think you are interested in. In the female gymnast example, I recommended that my student consider looking for studies of ballerinas, who also suffer sports injuries and around whom there is a similar culture of silence. It turned out that there was in fact research about my student’s particular questions, just not about the subjects she was interested in. You might do something similar. Don’t get stuck looking for too direct literature but think about the broader phenomenon of interest or analogous cases.

Read Outside the Canon

Some scholars’ work gets cited by everyone all the time. To some extent, this is a very good thing, as it helps establish the discipline. For example, there are a lot of “Bourdieu scholars” out there (myself included) who draw ideas, concepts, and quoted passages from Bourdieu. This makes us recognizable to one another and is a way of sharing a common language (e.g., where “cultural capital” has a particular meaning to those versed in Bourdieusian theory). There are empirical studies that get cited over and over again because they are excellent studies but also because there is an “echo chamber effect” going on, where knowing to cite this study marks you as part of the club, in the know, and so on. But here’s the problem with this: there are hundreds if not thousands of excellent studies out there that fail to get appreciated because they are crowded out by the canon. Sometimes this happens because they are published in “lower-ranked” journals and are never read by a lot of scholars who don’t have time to read anything other than the “big three” in their field. Other times this happens because the author falls outside of the dominant social networks in the field and thus is unmentored and fails to get noticed by those who publish a lot in those highly ranked and visible spaces. Scholars who fall outside the dominant social networks and who publish outside of the top-ranked journals are in no way less insightful than their peers, and their studies may be just as rigorous and relevant to your work, so it is important for you to take some time to read outside the canon. Due to how a person’s race, gender, and class operate in the academy, there is also a matter of social justice and ethical responsibility involved here: “When you focus on the most-cited research, you’re more likely to miss relevant research by women and especially women of color, whose research tends to be under-cited in most fields. You’re also more likely to miss new research, research by junior scholars, and research in other disciplines that could inform your work. Essentially, it is important to read and cite responsibly, which means checking that you’re not just reading and citing the same white men and the same old studies that everyone has cited before you” ( Calarco 2020:112 ).

Consider Multiple Uses for Literature

Throughout this chapter, I’ve referred to the literature of interest in a rather abstract way, as what is relevant to your study. But there are many different ways previous research can be relevant to your study. The most basic use of the literature is the “findings”—for example, “So-and-so found that Canadian working-class students were concerned about ‘fitting in’ to the culture of college, and I am going to look at a similar question here in the US.” But the literature may be of interest not for its findings but theoretically—for example, employing concepts that you want to employ in your own study. Bourdieu’s definition of social capital may have emerged in a study of French professors, but it can still be relevant in a study of, say, how parents make choices about what preschools to send their kids to (also a good example of lateral thinking!).

If you are engaged in some novel methodological form of data collection or analysis, you might look for previous literature that has attempted that. I would not recommend this for undergraduate research projects, but for graduate students who are considering “breaking the mold,” find out if anyone has been there before you. Even if their study has absolutely nothing else in common with yours, it is important to acknowledge that previous work.

Describing Gaps in the Literature

First, be careful! Although it is common to explain how your research adds to, builds upon, and fills in gaps in the previous research (see all four literature review examples in this chapter for this), there is a fine line between describing the gaps and misrepresenting previous literature by failing to conduct a thorough review of the literature. A little humility can make a big difference in your presentation. Instead of “This is the first study that has looked at how firefighters juggle childcare during forest fire season,” say, “I use the previous literature on how working parents juggling childcare and the previous ethnographic studies of firefighters to explore how firefighters juggle childcare during forest fire season.” You can even add, “To my knowledge, no one has conducted an ethnographic study in this specific area, although what we have learned from X about childcare and from Y about firefighters would lead us to expect Z here.” Read more literature review sections to see how others have described the “gaps” they are filling.

Use Concept Mapping

Concept mapping is a helpful tool for getting your thoughts in order and is particularly helpful when thinking about the “literature” foundational to your particular study. Concept maps are also known as mind maps, which is a delightful way to think about them. Your brain is probably abuzz with competing ideas in the early stages of your research design. Write/draw them on paper, and then try to categorize and move the pieces around into “clusters” that make sense to you. Going back to the gymnasts example, my student might have begun by jotting down random words of interest: gymnasts * sports * coaches * female gymnasts * stress * injury * don’t complain * women in sports * bad coaching * anxiety/stress * careers in sports * pain. She could then have begun clustering these into relational categories (bad coaching, don’t complain culture) and simple “event” categories (injury, stress). This might have led her to think about reviewing literature in these two separate aspects and then literature that put them together. There is no correct way to draw a concept map, as they are wonderfully specific to your mind. There are many examples you can find online.

Ask Yourself, “How Is This Sociology (or Political Science or Public Policy, Etc.)?”

Rubin ( 2021:82 ) offers this suggestion instead of asking yourself the “So what?” question to get you thinking about what bridges there are between your study and the body of research in your particular discipline. This is particularly helpful for thinking about theory. Rubin further suggests that if you are really stumped, ask yourself, “What is the really big question that all [fill in your discipline here] care about?” For sociology, it might be “inequality,” which would then help you think about theories of inequality that might be helpful in framing your study on whatever it is you are studying—OnlyFans? Childcare during COVID? Aging in America? I can think of some interesting ways to frame questions about inequality for any of those topics. You can further narrow it by focusing on particular aspects of inequality (Gender oppression? Racial exclusion? Heteronormativity?). If your discipline is public policy, the big questions there might be, How does policy get enacted, and what makes a policy effective? You can then take whatever your particular policy interest is—tax reform, student debt relief, cap-and-trade regulations—and apply those big questions. Doing so would give you a handle on what is otherwise an intolerably vague subject (e.g., What about student debt relief?).

Sometimes finding you are in new territory means you’ve hit the jackpot, and sometimes it means you’ve traveled out of bounds for your discipline. The jackpot scenario is wonderful. You are doing truly innovative research that is combining multiple literatures or is addressing a new or under-examined phenomenon of interest, and your research has the potential to be groundbreaking. Congrats! But that’s really hard to do, and it might be more likely that you’ve traveled out of bounds, by which I mean, you are no longer in your discipline . It might be that no one has written about this thing—at least within your field— because no one in your field actually cares about this topic . ( Rubin 2021:83 ; emphases added)

Don’t Treat This as a Chore

Don’t treat the literature review as a chore that has to be completed, but see it for what it really is—you are building connections to other researchers out there. You want to represent your discipline or area of study fairly and adequately. Demonstrate humility and your knowledge of previous research. Be part of the conversation.

Supplement: Two More Literature Review Examples

Elites by harvey ( 2011 ).

In the last two decades, there has been a small but growing literature on elites. In part, this has been a result of the resurgence of ethnographic research such as interviews, focus groups, case studies, and participant observation but also because scholars have become increasingly interested in understanding the perspectives and behaviors of leaders in business, politics, and society as a whole. Yet until recently, our understanding of some of the methodological challenges of researching elites has lagged behind our rush to interview them.

There is no clear-cut definition of the term elite, and given its broad understanding across the social sciences, scholars have tended to adopt different approaches. Zuckerman (1972) uses the term ultraelites to describe individuals who hold a significant amount of power within a group that is already considered elite. She argues, for example, that US senators constitute part of the country’s political elite but that among them are the ultraelites: a “subset of particularly powerful or prestigious influentials” (160). She suggests that there is a hierarchy of status within elite groups. McDowell (1998) analyses a broader group of “professional elites” who are employees working at different levels for merchant and investment banks in London. She classifies this group as elite because they are “highly skilled, professionally competent, and class-specific” (2135). Parry (1998:2148) uses the term hybrid elites in the context of the international trade of genetic material because she argues that critical knowledge exists not in traditional institutions “but rather as increasingly informal, hybridised, spatially fragmented, and hence largely ‘invisible,’ networks of elite actors.” Given the undertheorization of the term elite, Smith (2006) recognizes why scholars have shaped their definitions to match their respondents . However, she is rightly critical of the underlying assumption that those who hold professional positions necessarily exert as much influence as initially perceived. Indeed, job titles can entirely misrepresent the role of workers and therefore are by no means an indicator of elite status (Harvey 2010).

Many scholars have used the term elite in a relational sense, defining them either in terms of their social position compared to the researcher or compared to the average person in society (Stephens 2007). The problem with this definition is there is no guarantee that an elite subject will necessarily translate this power and authority in an interview setting. Indeed, Smith (2006) found that on the few occasions she experienced respondents wanting to exert their authority over her, it was not from elites but from relatively less senior workers. Furthermore, although business and political elites often receive extensive media training, they are often scrutinized by television and radio journalists and therefore can also feel threatened in an interview, particularly in contexts that are less straightforward to prepare for such as academic interviews. On several occasions, for instance, I have been asked by elite respondents or their personal assistants what they need to prepare for before the interview, which suggests that they consider the interview as some form of challenge or justification for what they do.

In many cases, it is not necessarily the figureheads or leaders of organizations and institutions who have the greatest claim to elite status but those who hold important social networks, social capital, and strategic positions within social structures because they are better able to exert influence (Burt 1992; Parry 1998; Smith 2005; Woods 1998). An elite status can also change, with people both gaining and losing theirs over time. In addition, it is geographically specific, with people holding elite status in some but not all locations. In short, it is clear that the term elite can mean many things in different contexts, which explains the range of definitions. The purpose here is not to critique these other definitions but rather to highlight the variety of perspectives.

When referring to my research, I define elites as those who occupy senior-management- and board-level positions within organizations. This is a similar scope of definition to Zuckerman’s (1972) but focuses on a level immediately below her ultraelite subjects. My definition is narrower than McDowell’s (1998) because it is clear in the context of my research that these people have significant decision-making influence within and outside of the firm and therefore present a unique challenge to interview. I deliberately use the term elite more broadly when drawing on examples from the theoretical literature in order to compare my experiences with those who have researched similar groups.

”Changing Dispositions among the Upwardly Mobile” by Curl, Lareau, and Wu ( 2018 )

There is growing interest in the role of cultural practices in undergirding the social stratification system. For example, Lamont et al. (2014) critically assess the preoccupation with economic dimensions of social stratification and call for more developed cultural models of the transmission of inequality. The importance of cultural factors in the maintenance of social inequality has also received empirical attention from some younger scholars, including Calarco (2011, 2014) and Streib (2015). Yet questions remain regarding the degree to which economic position is tied to cultural sensibilities and the ways in which these cultural sensibilities are imprinted on the self or are subject to change. Although habitus is a core concept in Bourdieu’s theory of social reproduction, there is limited empirical attention to the precise areas of the habitus that can be subject to change during upward mobility as well as the ramifications of these changes for family life.

In Bourdieu’s (1984) highly influential work on the importance of class-based cultural dispositions, habitus is defined as a “durable system of dispositions” created in childhood. The habitus provides a “matrix of perceptions” that seems natural while also structuring future actions and pathways. In many of his writings, Bourdieu emphasized the durability of cultural tastes and dispositions and did not consider empirically whether these dispositions might be changed or altered throughout one’s life (Swartz 1997). His theoretical work does permit the possibility of upward mobility and transformation, however, through the ability of the habitus to “improvise” or “change” due to “new experiences” (Friedman 2016:131). Researchers have differed in opinion on the durability of the habitus and its ability to change (King 2000). Based on marital conflict in cross-class marriages, for instance, Streib (2015) argues that cultural dispositions of individuals raised in working-class families are deeply embedded and largely unchanging. In a somewhat different vein, Horvat and Davis (2011:152) argue that young adults enrolled in an alternative educational program undergo important shifts in their self-perception, such as “self-esteem” and their “ability to accomplish something of value.” Others argue there is variability in the degree to which habitus changes dependent on life experience and personality (Christodoulou and Spyridakis 2016). Recently, additional studies have investigated the habitus as it intersects with lifestyle through the lens of meaning making (Ambrasat et al. 2016). There is, therefore, ample discussion of class-based cultural practices in self-perception (Horvat and Davis 2011), lifestyle (Ambrasat et al. 2016), and other forms of taste (Andrews 2012; Bourdieu 1984), yet researchers have not sufficiently delineated which aspects of the habitus might change through upward mobility or which specific dimensions of life prompt moments of class-based conflict.

Bourdieu (1999:511; 2004) acknowledged simmering tensions between the durable aspects of habitus and those aspects that have been transformed—that is, a “fractured” or “cleft” habitus. Others have explored these tensions as a “divided” or “fragmented” habitus (Baxter and Britton 2001; Lee and Kramer 2013). Each of these conceptions of the habitus implies that changes in cultural dispositions are possible but come with costs. Exploration of the specific aspects of one’s habitus that can change and generate conflict contributes to this literature.

Scholars have also studied the costs associated with academic success for working-class undergraduates (Hurst 2010; Lee and Kramer 2013; London 1989; Reay 2017; Rondini 2016; Stuber 2011), but we know little about the lasting effects on adults. For instance, Lee and Kramer (2013) point to cross-class tensions as family and friends criticize upwardly mobile individuals for their newly acquired cultural dispositions. Documenting the tension many working-class students experience with their friends and families of origin, they find that the source of their pain or struggle is “shaped not only by their interactions with non-mobile family and friends but also within their own minds, by their own assessments of their social positions, and by how those positions are interpreted by others” (Lee and Kramer 2013:29). Hurst (2010) also explores the experiences of undergraduates who have been academically successful and the costs associated with that success. She finds that decisions about “class allegiance and identity” are required aspects of what it means to “becom[e] educated” (4) and that working-class students deal with these cultural changes differently. Jack (2014, 2016) also argues that there is diversity among lower-income students, which yields varied college experiences. Naming two groups, the “doubly disadvantaged” and the “privileged poor,” he argues that previous experience with “elite environments” (2014:456) prior to college informs students’ ability to take on dominant cultural practices, particularly around engagement, such as help seeking or meeting with professors (2016). These studies shed light on the role college might play as a “lever for mobility” (2016:15) and discuss the pain and difficulty associated with upward mobility among undergraduates, but the studies do not illuminate how these tensions unfold in adulthood. Neither have they sufficiently addressed potential enduring tensions with extended family members as well as the specific nature of the difficulties.

Some scholars point to the positive outcomes upwardly mobile youth (Lehmann 2009) and adults (Stuber 2005) experience when they maintain a different habitus than their newly acquired class position, although, as Jack (2014, 2016) shows, those experiences may vary depending on one’s experience with elite environments in their youth. Researchers have not sufficiently explored the specific aspects of the habitus that upwardly mobile adults change or the conflicts that emerge with family and childhood friends as they reach adulthood and experience colliding social worlds. We contribute to this scholarship with clear examples of self-reported changes to one’s cultural dispositions in three specific areas: “horizons,” food and health, and communication. We link these changes to enduring tension with family members, friends, and colleagues and explore varied responses to this tension based on race.

Usually, a literature review takes time and becomes a demanding step in any research project. The proposal presented in this article intends to structure this work in an organised and transparent way for all project participants and the structured elaboration of its report. Integrating qualitative and quantitative analysis provides opportunities to carry out a solid, practical, and in-depth literature review. The purpose of this article is to present a guide that explores the potentials of qualitative and quantitative analysis integration to develop a solid and replicable literature review. The paper proposes an integrative approach comprising six steps: 1) research design; 2) Data Collection for bibliometric analysis; 3) Search string refinement; 4) Bibliometric analysis; 5) qualitative analysis; and 6) report and dissemination of research results. These guidelines can facilitate the bibliographic analysis process and relevant article sample selection. Once the sample of publications is defined, it is possible to conduct a deep analysis through Content Analysis. Software tools, such as R Bibliometrix, VOSviewer, Gephi, yEd and webQDA, can be used for practical work during all collection, analysis, and reporting processes. From a large amount of data, selecting a sample of relevant literature is facilitated by interpreting bibliometric results. The specification of the methodology allows the replication and updating of the literature review in an interactive, systematic, and collaborative way giving a more transparent and organised approach to improving the literature review.

The systematic methods overview used as a worked example in this article (Gentles SJ, Charles C, Ploeg J, McKibbon KA: Sampling in qualitative research: insights from an overview of the methods literature. The Qual Rep 2015, 20(11):1772-1789) is available from http://nsuworks.nova.edu/tqr/vol20/iss11/5 .

Overviews of methods are potentially useful means to increase clarity and enhance collective understanding of specific methods topics that may be characterized by ambiguity, inconsistency, or a lack of comprehensiveness. This type of review represents a distinct literature synthesis method, although to date, its methodology remains relatively undeveloped despite several aspects that demand unique review procedures. The purpose of this paper is to initiate discussion about what a rigorous systematic approach to reviews of methods, referred to here as systematic methods overviews , might look like by providing tentative suggestions for approaching specific challenges likely to be encountered. The guidance offered here was derived from experience conducting a systematic methods overview on the topic of sampling in qualitative research.

The guidance is organized into several principles that highlight specific objectives for this type of review given the common challenges that must be overcome to achieve them. Optional strategies for achieving each principle are also proposed, along with discussion of how they were successfully implemented in the overview on sampling. We describe seven paired principles and strategies that address the following aspects: delimiting the initial set of publications to consider, searching beyond standard bibliographic databases, searching without the availability of relevant metadata, selecting publications on purposeful conceptual grounds, defining concepts and other information to abstract iteratively, accounting for inconsistent terminology used to describe specific methods topics, and generating rigorous verifiable analytic interpretations. Since a broad aim in systematic methods overviews is to describe and interpret the relevant literature in qualitative terms, we suggest that iterative decision making at various stages of the review process, and a rigorous qualitative approach to analysis are necessary features of this review type.

Conclusions

We believe that the principles and strategies provided here will be useful to anyone choosing to undertake a systematic methods overview. This paper represents an initial effort to promote high quality critical evaluations of the literature regarding problematic methods topics, which have the potential to promote clearer, shared understandings, and accelerate advances in research methods. Further work is warranted to develop more definitive guidance.

Electronic supplementary material

The online version of this article (doi:10.1186/s13643-016-0343-0) contains supplementary material, which is available to authorized users.

While reviews of methods are not new, they represent a distinct review type whose methodology remains relatively under-addressed in the literature despite the clear implications for unique review procedures. One of few examples to describe it is a chapter containing reflections of two contributing authors in a book of 21 reviews on methodological topics compiled for the British National Health Service, Health Technology Assessment Program [ 1 ]. Notable is their observation of how the differences between the methods reviews and conventional quantitative systematic reviews, specifically attributable to their varying content and purpose, have implications for defining what qualifies as systematic. While the authors describe general aspects of “systematicity” (including rigorous application of a methodical search, abstraction, and analysis), they also describe a high degree of variation within the category of methods reviews itself and so offer little in the way of concrete guidance. In this paper, we present tentative concrete guidance, in the form of a preliminary set of proposed principles and optional strategies, for a rigorous systematic approach to reviewing and evaluating the literature on quantitative or qualitative methods topics. For purposes of this article, we have used the term systematic methods overview to emphasize the notion of a systematic approach to such reviews.

The conventional focus of rigorous literature reviews (i.e., review types for which systematic methods have been codified, including the various approaches to quantitative systematic reviews [ 2 – 4 ], and the numerous forms of qualitative and mixed methods literature synthesis [ 5 – 10 ]) is to synthesize empirical research findings from multiple studies. By contrast, the focus of overviews of methods, including the systematic approach we advocate, is to synthesize guidance on methods topics. The literature consulted for such reviews may include the methods literature, methods-relevant sections of empirical research reports, or both. Thus, this paper adds to previous work published in this journal—namely, recent preliminary guidance for conducting reviews of theory [ 11 ]—that has extended the application of systematic review methods to novel review types that are concerned with subject matter other than empirical research findings.

Published examples of methods overviews illustrate the varying objectives they can have. One objective is to establish methodological standards for appraisal purposes. For example, reviews of existing quality appraisal standards have been used to propose universal standards for appraising the quality of primary qualitative research [ 12 ] or evaluating qualitative research reports [ 13 ]. A second objective is to survey the methods-relevant sections of empirical research reports to establish current practices on methods use and reporting practices, which Moher and colleagues [ 14 ] recommend as a means for establishing the needs to be addressed in reporting guidelines (see, for example [ 15 , 16 ]). A third objective for a methods review is to offer clarity and enhance collective understanding regarding a specific methods topic that may be characterized by ambiguity, inconsistency, or a lack of comprehensiveness within the available methods literature. An example of this is a overview whose objective was to review the inconsistent definitions of intention-to-treat analysis (the methodologically preferred approach to analyze randomized controlled trial data) that have been offered in the methods literature and propose a solution for improving conceptual clarity [ 17 ]. Such reviews are warranted because students and researchers who must learn or apply research methods typically lack the time to systematically search, retrieve, review, and compare the available literature to develop a thorough and critical sense of the varied approaches regarding certain controversial or ambiguous methods topics.

While systematic methods overviews , as a review type, include both reviews of the methods literature and reviews of methods-relevant sections from empirical study reports, the guidance provided here is primarily applicable to reviews of the methods literature since it was derived from the experience of conducting such a review [ 18 ], described below. To our knowledge, there are no well-developed proposals on how to rigorously conduct such reviews. Such guidance would have the potential to improve the thoroughness and credibility of critical evaluations of the methods literature, which could increase their utility as a tool for generating understandings that advance research methods, both qualitative and quantitative. Our aim in this paper is thus to initiate discussion about what might constitute a rigorous approach to systematic methods overviews. While we hope to promote rigor in the conduct of systematic methods overviews wherever possible, we do not wish to suggest that all methods overviews need be conducted to the same standard. Rather, we believe that the level of rigor may need to be tailored pragmatically to the specific review objectives, which may not always justify the resource requirements of an intensive review process.

The example systematic methods overview on sampling in qualitative research

The principles and strategies we propose in this paper are derived from experience conducting a systematic methods overview on the topic of sampling in qualitative research [ 18 ]. The main objective of that methods overview was to bring clarity and deeper understanding of the prominent concepts related to sampling in qualitative research (purposeful sampling strategies, saturation, etc.). Specifically, we interpreted the available guidance, commenting on areas lacking clarity, consistency, or comprehensiveness (without proposing any recommendations on how to do sampling). This was achieved by a comparative and critical analysis of publications representing the most influential (i.e., highly cited) guidance across several methodological traditions in qualitative research.

The specific methods and procedures for the overview on sampling [ 18 ] from which our proposals are derived were developed both after soliciting initial input from local experts in qualitative research and an expert health librarian (KAM) and through ongoing careful deliberation throughout the review process. To summarize, in that review, we employed a transparent and rigorous approach to search the methods literature, selected publications for inclusion according to a purposeful and iterative process, abstracted textual data using structured abstraction forms, and analyzed (synthesized) the data using a systematic multi-step approach featuring abstraction of text, summary of information in matrices, and analytic comparisons.

For this article, we reflected on both the problems and challenges encountered at different stages of the review and our means for selecting justifiable procedures to deal with them. Several principles were then derived by considering the generic nature of these problems, while the generalizable aspects of the procedures used to address them formed the basis of optional strategies. Further details of the specific methods and procedures used in the overview on qualitative sampling are provided below to illustrate both the types of objectives and challenges that reviewers will likely need to consider and our approach to implementing each of the principles and strategies.

Organization of the guidance into principles and strategies

For the purposes of this article, principles are general statements outlining what we propose are important aims or considerations within a particular review process, given the unique objectives or challenges to be overcome with this type of review. These statements follow the general format, “considering the objective or challenge of X, we propose Y to be an important aim or consideration.” Strategies are optional and flexible approaches for implementing the previous principle outlined. Thus, generic challenges give rise to principles, which in turn give rise to strategies.

We organize the principles and strategies below into three sections corresponding to processes characteristic of most systematic literature synthesis approaches: literature identification and selection ; data abstraction from the publications selected for inclusion; and analysis , including critical appraisal and synthesis of the abstracted data. Within each section, we also describe the specific methodological decisions and procedures used in the overview on sampling in qualitative research [ 18 ] to illustrate how the principles and strategies for each review process were applied and implemented in a specific case. We expect this guidance and accompanying illustrations will be useful for anyone considering engaging in a methods overview, particularly those who may be familiar with conventional systematic review methods but may not yet appreciate some of the challenges specific to reviewing the methods literature.

Results and discussion

Literature identification and selection.

The identification and selection process includes search and retrieval of publications and the development and application of inclusion and exclusion criteria to select the publications that will be abstracted and analyzed in the final review. Literature identification and selection for overviews of the methods literature is challenging and potentially more resource-intensive than for most reviews of empirical research. This is true for several reasons that we describe below, alongside discussion of the potential solutions. Additionally, we suggest in this section how the selection procedures can be chosen to match the specific analytic approach used in methods overviews.

Delimiting a manageable set of publications

One aspect of methods overviews that can make identification and selection challenging is the fact that the universe of literature containing potentially relevant information regarding most methods-related topics is expansive and often unmanageably so. Reviewers are faced with two large categories of literature: the methods literature , where the possible publication types include journal articles, books, and book chapters; and the methods-relevant sections of empirical study reports , where the possible publication types include journal articles, monographs, books, theses, and conference proceedings. In our systematic overview of sampling in qualitative research, exhaustively searching (including retrieval and first-pass screening) all publication types across both categories of literature for information on a single methods-related topic was too burdensome to be feasible. The following proposed principle follows from the need to delimit a manageable set of literature for the review.

Principle #1:

Considering the broad universe of potentially relevant literature, we propose that an important objective early in the identification and selection stage is to delimit a manageable set of methods-relevant publications in accordance with the objectives of the methods overview.

Strategy #1:

To limit the set of methods-relevant publications that must be managed in the selection process, reviewers have the option to initially review only the methods literature, and exclude the methods-relevant sections of empirical study reports, provided this aligns with the review’s particular objectives.

We propose that reviewers are justified in choosing to select only the methods literature when the objective is to map out the range of recognized concepts relevant to a methods topic, to summarize the most authoritative or influential definitions or meanings for methods-related concepts, or to demonstrate a problematic lack of clarity regarding a widely established methods-related concept and potentially make recommendations for a preferred approach to the methods topic in question. For example, in the case of the methods overview on sampling [ 18 ], the primary aim was to define areas lacking in clarity for multiple widely established sampling-related topics. In the review on intention-to-treat in the context of missing outcome data [ 17 ], the authors identified a lack of clarity based on multiple inconsistent definitions in the literature and went on to recommend separating the issue of how to handle missing outcome data from the issue of whether an intention-to-treat analysis can be claimed.

In contrast to strategy #1, it may be appropriate to select the methods-relevant sections of empirical study reports when the objective is to illustrate how a methods concept is operationalized in research practice or reported by authors. For example, one could review all the publications in 2 years’ worth of issues of five high-impact field-related journals to answer questions about how researchers describe implementing a particular method or approach, or to quantify how consistently they define or report using it. Such reviews are often used to highlight gaps in the reporting practices regarding specific methods, which may be used to justify items to address in reporting guidelines (for example, [ 14 – 16 ]).

It is worth recognizing that other authors have advocated broader positions regarding the scope of literature to be considered in a review, expanding on our perspective. Suri [ 10 ] (who, like us, emphasizes how different sampling strategies are suitable for different literature synthesis objectives) has, for example, described a two-stage literature sampling procedure (pp. 96–97). First, reviewers use an initial approach to conduct a broad overview of the field—for reviews of methods topics, this would entail an initial review of the research methods literature. This is followed by a second more focused stage in which practical examples are purposefully selected—for methods reviews, this would involve sampling the empirical literature to illustrate key themes and variations. While this approach is seductive in its capacity to generate more in depth and interpretive analytic findings, some reviewers may consider it too resource-intensive to include the second step no matter how selective the purposeful sampling. In the overview on sampling where we stopped after the first stage [ 18 ], we discussed our selective focus on the methods literature as a limitation that left opportunities for further analysis of the literature. We explicitly recommended, for example, that theoretical sampling was a topic for which a future review of the methods sections of empirical reports was justified to answer specific questions identified in the primary review.

Ultimately, reviewers must make pragmatic decisions that balance resource considerations, combined with informed predictions about the depth and complexity of literature available on their topic, with the stated objectives of their review. The remaining principles and strategies apply primarily to overviews that include the methods literature, although some aspects may be relevant to reviews that include empirical study reports.

Searching beyond standard bibliographic databases

An important reality affecting identification and selection in overviews of the methods literature is the increased likelihood for relevant publications to be located in sources other than journal articles (which is usually not the case for overviews of empirical research, where journal articles generally represent the primary publication type). In the overview on sampling [ 18 ], out of 41 full-text publications retrieved and reviewed, only 4 were journal articles, while 37 were books or book chapters. Since many books and book chapters did not exist electronically, their full text had to be physically retrieved in hardcopy, while 11 publications were retrievable only through interlibrary loan or purchase request. The tasks associated with such retrieval are substantially more time-consuming than electronic retrieval. Since a substantial proportion of methods-related guidance may be located in publication types that are less comprehensively indexed in standard bibliographic databases, identification and retrieval thus become complicated processes.

Principle #2:

Considering that important sources of methods guidance can be located in non-journal publication types (e.g., books, book chapters) that tend to be poorly indexed in standard bibliographic databases, it is important to consider alternative search methods for identifying relevant publications to be further screened for inclusion.

Strategy #2:

To identify books, book chapters, and other non-journal publication types not thoroughly indexed in standard bibliographic databases, reviewers may choose to consult one or more of the following less standard sources: Google Scholar, publisher web sites, or expert opinion.

In the case of the overview on sampling in qualitative research [ 18 ], Google Scholar had two advantages over other standard bibliographic databases: it indexes and returns records of books and book chapters likely to contain guidance on qualitative research methods topics; and it has been validated as providing higher citation counts than ISI Web of Science (a producer of numerous bibliographic databases accessible through institutional subscription) for several non-biomedical disciplines including the social sciences where qualitative research methods are prominently used [ 19 – 21 ]. While we identified numerous useful publications by consulting experts, the author publication lists generated through Google Scholar searches were uniquely useful to identify more recent editions of methods books identified by experts.

Searching without relevant metadata

Determining what publications to select for inclusion in the overview on sampling [ 18 ] could only rarely be accomplished by reviewing the publication’s metadata. This was because for the many books and other non-journal type publications we identified as possibly relevant, the potential content of interest would be located in only a subsection of the publication. In this common scenario for reviews of the methods literature (as opposed to methods overviews that include empirical study reports), reviewers will often be unable to employ standard title, abstract, and keyword database searching or screening as a means for selecting publications.

Principle #3:

Considering that the presence of information about the topic of interest may not be indicated in the metadata for books and similar publication types, it is important to consider other means of identifying potentially useful publications for further screening.

Strategy #3:

One approach to identifying potentially useful books and similar publication types is to consider what classes of such publications (e.g., all methods manuals for a certain research approach) are likely to contain relevant content, then identify, retrieve, and review the full text of corresponding publications to determine whether they contain information on the topic of interest.

In the example of the overview on sampling in qualitative research [ 18 ], the topic of interest (sampling) was one of numerous topics covered in the general qualitative research methods manuals. Consequently, examples from this class of publications first had to be identified for retrieval according to non-keyword-dependent criteria. Thus, all methods manuals within the three research traditions reviewed (grounded theory, phenomenology, and case study) that might contain discussion of sampling were sought through Google Scholar and expert opinion, their full text obtained, and hand-searched for relevant content to determine eligibility. We used tables of contents and index sections of books to aid this hand searching.

Purposefully selecting literature on conceptual grounds

A final consideration in methods overviews relates to the type of analysis used to generate the review findings. Unlike quantitative systematic reviews where reviewers aim for accurate or unbiased quantitative estimates—something that requires identifying and selecting the literature exhaustively to obtain all relevant data available (i.e., a complete sample)—in methods overviews, reviewers must describe and interpret the relevant literature in qualitative terms to achieve review objectives. In other words, the aim in methods overviews is to seek coverage of the qualitative concepts relevant to the methods topic at hand. For example, in the overview of sampling in qualitative research [ 18 ], achieving review objectives entailed providing conceptual coverage of eight sampling-related topics that emerged as key domains. The following principle recognizes that literature sampling should therefore support generating qualitative conceptual data as the input to analysis.

Principle #4:

Since the analytic findings of a systematic methods overview are generated through qualitative description and interpretation of the literature on a specified topic, selection of the literature should be guided by a purposeful strategy designed to achieve adequate conceptual coverage (i.e., representing an appropriate degree of variation in relevant ideas) of the topic according to objectives of the review.

Strategy #4:

One strategy for choosing the purposeful approach to use in selecting the literature according to the review objectives is to consider whether those objectives imply exploring concepts either at a broad overview level, in which case combining maximum variation selection with a strategy that limits yield (e.g., critical case, politically important, or sampling for influence—described below) may be appropriate; or in depth, in which case purposeful approaches aimed at revealing innovative cases will likely be necessary.

In the methods overview on sampling, the implied scope was broad since we set out to review publications on sampling across three divergent qualitative research traditions—grounded theory, phenomenology, and case study—to facilitate making informative conceptual comparisons. Such an approach would be analogous to maximum variation sampling.

At the same time, the purpose of that review was to critically interrogate the clarity, consistency, and comprehensiveness of literature from these traditions that was “most likely to have widely influenced students’ and researchers’ ideas about sampling” (p. 1774) [ 18 ]. In other words, we explicitly set out to review and critique the most established and influential (and therefore dominant) literature, since this represents a common basis of knowledge among students and researchers seeking understanding or practical guidance on sampling in qualitative research. To achieve this objective, we purposefully sampled publications according to the criterion of influence , which we operationalized as how often an author or publication has been referenced in print or informal discourse. This second sampling approach also limited the literature we needed to consider within our broad scope review to a manageable amount.

To operationalize this strategy of sampling for influence , we sought to identify both the most influential authors within a qualitative research tradition (all of whose citations were subsequently screened) and the most influential publications on the topic of interest by non-influential authors. This involved a flexible approach that combined multiple indicators of influence to avoid the dilemma that any single indicator might provide inadequate coverage. These indicators included bibliometric data (h-index for author influence [ 22 ]; number of cites for publication influence), expert opinion, and cross-references in the literature (i.e., snowball sampling). As a final selection criterion, a publication was included only if it made an original contribution in terms of novel guidance regarding sampling or a related concept; thus, purely secondary sources were excluded. Publish or Perish software (Anne-Wil Harzing; available at http://www.harzing.com/resources/publish-or-perish ) was used to generate bibliometric data via the Google Scholar database. Figure 1 illustrates how identification and selection in the methods overview on sampling was a multi-faceted and iterative process. The authors selected as influential, and the publications selected for inclusion or exclusion are listed in Additional file 1 (Matrices 1, 2a, 2b).

Literature identification and selection process used in the methods overview on sampling [ 18 ]

In summary, the strategies of seeking maximum variation and sampling for influence were employed in the sampling overview to meet the specific review objectives described. Reviewers will need to consider the full range of purposeful literature sampling approaches at their disposal in deciding what best matches the specific aims of their own reviews. Suri [ 10 ] has recently retooled Patton’s well-known typology of purposeful sampling strategies (originally intended for primary research) for application to literature synthesis, providing a useful resource in this respect.

Data abstraction

The purpose of data abstraction in rigorous literature reviews is to locate and record all data relevant to the topic of interest from the full text of included publications, making them available for subsequent analysis. Conventionally, a data abstraction form—consisting of numerous distinct conceptually defined fields to which corresponding information from the source publication is recorded—is developed and employed. There are several challenges, however, to the processes of developing the abstraction form and abstracting the data itself when conducting methods overviews, which we address here. Some of these problems and their solutions may be familiar to those who have conducted qualitative literature syntheses, which are similarly conceptual.

Iteratively defining conceptual information to abstract

In the overview on sampling [ 18 ], while we surveyed multiple sources beforehand to develop a list of concepts relevant for abstraction (e.g., purposeful sampling strategies, saturation, sample size), there was no way for us to anticipate some concepts prior to encountering them in the review process. Indeed, in many cases, reviewers are unable to determine the complete set of methods-related concepts that will be the focus of the final review a priori without having systematically reviewed the publications to be included. Thus, defining what information to abstract beforehand may not be feasible.

Principle #5:

Considering the potential impracticality of defining a complete set of relevant methods-related concepts from a body of literature one has not yet systematically read, selecting and defining fields for data abstraction must often be undertaken iteratively. Thus, concepts to be abstracted can be expected to grow and change as data abstraction proceeds.

Strategy #5:

Reviewers can develop an initial form or set of concepts for abstraction purposes according to standard methods (e.g., incorporating expert feedback, pilot testing) and remain attentive to the need to iteratively revise it as concepts are added or modified during the review. Reviewers should document revisions and return to re-abstract data from previously abstracted publications as the new data requirements are determined.

In the sampling overview [ 18 ], we developed and maintained the abstraction form in Microsoft Word. We derived the initial set of abstraction fields from our own knowledge of relevant sampling-related concepts, consultation with local experts, and reviewing a pilot sample of publications. Since the publications in this review included a large proportion of books, the abstraction process often began by flagging the broad sections within a publication containing topic-relevant information for detailed review to identify text to abstract. When reviewing flagged text, the reviewer occasionally encountered an unanticipated concept significant enough to warrant being added as a new field to the abstraction form. For example, a field was added to capture how authors described the timing of sampling decisions, whether before (a priori) or after (ongoing) starting data collection, or whether this was unclear. In these cases, we systematically documented the modification to the form and returned to previously abstracted publications to abstract any information that might be relevant to the new field.

The logic of this strategy is analogous to the logic used in a form of research synthesis called best fit framework synthesis (BFFS) [ 23 – 25 ]. In that method, reviewers initially code evidence using an a priori framework they have selected. When evidence cannot be accommodated by the selected framework, reviewers then develop new themes or concepts from which they construct a new expanded framework. Both the strategy proposed and the BFFS approach to research synthesis are notable for their rigorous and transparent means to adapt a final set of concepts to the content under review.

Accounting for inconsistent terminology

An important complication affecting the abstraction process in methods overviews is that the language used by authors to describe methods-related concepts can easily vary across publications. For example, authors from different qualitative research traditions often use different terms for similar methods-related concepts. Furthermore, as we found in the sampling overview [ 18 ], there may be cases where no identifiable term, phrase, or label for a methods-related concept is used at all, and a description of it is given instead. This can make searching the text for relevant concepts based on keywords unreliable.

Principle #6:

Since accepted terms may not be used consistently to refer to methods concepts, it is necessary to rely on the definitions for concepts, rather than keywords, to identify relevant information in the publication to abstract.

Strategy #6:

An effective means to systematically identify relevant information is to develop and iteratively adjust written definitions for key concepts (corresponding to abstraction fields) that are consistent with and as inclusive of as much of the literature reviewed as possible. Reviewers then seek information that matches these definitions (rather than keywords) when scanning a publication for relevant data to abstract.

In the abstraction process for the sampling overview [ 18 ], we noted the several concepts of interest to the review for which abstraction by keyword was particularly problematic due to inconsistent terminology across publications: sampling , purposeful sampling , sampling strategy , and saturation (for examples, see Additional file 1 , Matrices 3a, 3b, 4). We iteratively developed definitions for these concepts by abstracting text from publications that either provided an explicit definition or from which an implicit definition could be derived, which was recorded in fields dedicated to the concept’s definition. Using a method of constant comparison, we used text from definition fields to inform and modify a centrally maintained definition of the corresponding concept to optimize its fit and inclusiveness with the literature reviewed. Table 1 shows, as an example, the final definition constructed in this way for one of the central concepts of the review, qualitative sampling .

Final definition for qualitative sampling , including methodological tradition-specific variations

Developed after numerous iterations in the methods overview on sampling [ 18 ]

We applied iteratively developed definitions when making decisions about what specific text to abstract for an existing field, which allowed us to abstract concept-relevant data even if no recognized keyword was used. For example, this was the case for the sampling-related concept, saturation , where the relevant text available for abstraction in one publication [ 26 ]—“to continue to collect data until nothing new was being observed or recorded, no matter how long that takes”—was not accompanied by any term or label whatsoever.

This comparative analytic strategy (and our approach to analysis more broadly as described in strategy #7, below) is analogous to the process of reciprocal translation —a technique first introduced for meta-ethnography by Noblit and Hare [ 27 ] that has since been recognized as a common element in a variety of qualitative metasynthesis approaches [ 28 ]. Reciprocal translation, taken broadly, involves making sense of a study’s findings in terms of the findings of the other studies included in the review. In practice, it has been operationalized in different ways. Melendez-Torres and colleagues developed a typology from their review of the metasynthesis literature, describing four overlapping categories of specific operations undertaken in reciprocal translation: visual representation, key paper integration, data reduction and thematic extraction, and line-by-line coding [ 28 ]. The approaches suggested in both strategies #6 and #7, with their emphasis on constant comparison, appear to fall within the line-by-line coding category.

Generating credible and verifiable analytic interpretations

The analysis in a systematic methods overview must support its more general objective, which we suggested above is often to offer clarity and enhance collective understanding regarding a chosen methods topic. In our experience, this involves describing and interpreting the relevant literature in qualitative terms. Furthermore, any interpretative analysis required may entail reaching different levels of abstraction, depending on the more specific objectives of the review. For example, in the overview on sampling [ 18 ], we aimed to produce a comparative analysis of how multiple sampling-related topics were treated differently within and among different qualitative research traditions. To promote credibility of the review, however, not only should one seek a qualitative analytic approach that facilitates reaching varying levels of abstraction but that approach must also ensure that abstract interpretations are supported and justified by the source data and not solely the product of the analyst’s speculative thinking.

Principle #7:

Considering the qualitative nature of the analysis required in systematic methods overviews, it is important to select an analytic method whose interpretations can be verified as being consistent with the literature selected, regardless of the level of abstraction reached.

Strategy #7:

We suggest employing the constant comparative method of analysis [ 29 ] because it supports developing and verifying analytic links to the source data throughout progressively interpretive or abstract levels. In applying this approach, we advise a rigorous approach, documenting how supportive quotes or references to the original texts are carried forward in the successive steps of analysis to allow for easy verification.

The analytic approach used in the methods overview on sampling [ 18 ] comprised four explicit steps, progressing in level of abstraction—data abstraction, matrices, narrative summaries, and final analytic conclusions (Fig. 2 ). While we have positioned data abstraction as the second stage of the generic review process (prior to Analysis), above, we also considered it as an initial step of analysis in the sampling overview for several reasons. First, it involved a process of constant comparisons and iterative decision-making about the fields to add or define during development and modification of the abstraction form, through which we established the range of concepts to be addressed in the review. At the same time, abstraction involved continuous analytic decisions about what textual quotes (ranging in size from short phrases to numerous paragraphs) to record in the fields thus created. This constant comparative process was analogous to open coding in which textual data from publications was compared to conceptual fields (equivalent to codes) or to other instances of data previously abstracted when constructing definitions to optimize their fit with the overall literature as described in strategy #6. Finally, in the data abstraction step, we also recorded our first interpretive thoughts in dedicated fields, providing initial material for the more abstract analytic steps.

Summary of progressive steps of analysis used in the methods overview on sampling [ 18 ]

In the second step of the analysis, we constructed topic-specific matrices , or tables, by copying relevant quotes from abstraction forms into the appropriate cells of matrices (for the complete set of analytic matrices developed in the sampling review, see Additional file 1 (matrices 3 to 10)). Each matrix ranged from one to five pages; row headings, nested three-deep, identified the methodological tradition, author, and publication, respectively; and column headings identified the concepts, which corresponded to abstraction fields. Matrices thus allowed us to make further comparisons across methodological traditions, and between authors within a tradition. In the third step of analysis, we recorded our comparative observations as narrative summaries , in which we used illustrative quotes more sparingly. In the final step, we developed analytic conclusions based on the narrative summaries about the sampling-related concepts within each methodological tradition for which clarity, consistency, or comprehensiveness of the available guidance appeared to be lacking. Higher levels of analysis thus built logically from the lower levels, enabling us to easily verify analytic conclusions by tracing the support for claims by comparing the original text of publications reviewed.

Integrative versus interpretive methods overviews

The analytic product of systematic methods overviews is comparable to qualitative evidence syntheses, since both involve describing and interpreting the relevant literature in qualitative terms. Most qualitative synthesis approaches strive to produce new conceptual understandings that vary in level of interpretation. Dixon-Woods and colleagues [ 30 ] elaborate on a useful distinction, originating from Noblit and Hare [ 27 ], between integrative and interpretive reviews. Integrative reviews focus on summarizing available primary data and involve using largely secure and well defined concepts to do so; definitions are used from an early stage to specify categories for abstraction (or coding) of data, which in turn supports their aggregation; they do not seek as their primary focus to develop or specify new concepts, although they may achieve some theoretical or interpretive functions. For interpretive reviews, meanwhile, the main focus is to develop new concepts and theories that integrate them, with the implication that the concepts developed become fully defined towards the end of the analysis. These two forms are not completely distinct, and “every integrative synthesis will include elements of interpretation, and every interpretive synthesis will include elements of aggregation of data” [ 30 ].

The example methods overview on sampling [ 18 ] could be classified as predominantly integrative because its primary goal was to aggregate influential authors’ ideas on sampling-related concepts; there were also, however, elements of interpretive synthesis since it aimed to develop new ideas about where clarity in guidance on certain sampling-related topics is lacking, and definitions for some concepts were flexible and not fixed until late in the review. We suggest that most systematic methods overviews will be classifiable as predominantly integrative (aggregative). Nevertheless, more highly interpretive methods overviews are also quite possible—for example, when the review objective is to provide a highly critical analysis for the purpose of generating new methodological guidance. In such cases, reviewers may need to sample more deeply (see strategy #4), specifically by selecting empirical research reports (i.e., to go beyond dominant or influential ideas in the methods literature) that are likely to feature innovations or instructive lessons in employing a given method.

In this paper, we have outlined tentative guidance in the form of seven principles and strategies on how to conduct systematic methods overviews, a review type in which methods-relevant literature is systematically analyzed with the aim of offering clarity and enhancing collective understanding regarding a specific methods topic. Our proposals include strategies for delimiting the set of publications to consider, searching beyond standard bibliographic databases, searching without the availability of relevant metadata, selecting publications on purposeful conceptual grounds, defining concepts and other information to abstract iteratively, accounting for inconsistent terminology, and generating credible and verifiable analytic interpretations. We hope the suggestions proposed will be useful to others undertaking reviews on methods topics in future.

As far as we are aware, this is the first published source of concrete guidance for conducting this type of review. It is important to note that our primary objective was to initiate methodological discussion by stimulating reflection on what rigorous methods for this type of review should look like, leaving the development of more complete guidance to future work. While derived from the experience of reviewing a single qualitative methods topic, we believe the principles and strategies provided are generalizable to overviews of both qualitative and quantitative methods topics alike. However, it is expected that additional challenges and insights for conducting such reviews have yet to be defined. Thus, we propose that next steps for developing more definitive guidance should involve an attempt to collect and integrate other reviewers’ perspectives and experiences in conducting systematic methods overviews on a broad range of qualitative and quantitative methods topics. Formalized guidance and standards would improve the quality of future methods overviews, something we believe has important implications for advancing qualitative and quantitative methodology. When undertaken to a high standard, rigorous critical evaluations of the available methods guidance have significant potential to make implicit controversies explicit, and improve the clarity and precision of our understandings of problematic qualitative or quantitative methods issues.

A review process central to most types of rigorous reviews of empirical studies, which we did not explicitly address in a separate review step above, is quality appraisal . The reason we have not treated this as a separate step stems from the different objectives of the primary publications included in overviews of the methods literature (i.e., providing methodological guidance) compared to the primary publications included in the other established review types (i.e., reporting findings from single empirical studies). This is not to say that appraising quality of the methods literature is not an important concern for systematic methods overviews. Rather, appraisal is much more integral to (and difficult to separate from) the analysis step, in which we advocate appraising clarity, consistency, and comprehensiveness—the quality appraisal criteria that we suggest are appropriate for the methods literature. As a second important difference regarding appraisal, we currently advocate appraising the aforementioned aspects at the level of the literature in aggregate rather than at the level of individual publications. One reason for this is that methods guidance from individual publications generally builds on previous literature, and thus we feel that ahistorical judgments about comprehensiveness of single publications lack relevance and utility. Additionally, while different methods authors may express themselves less clearly than others, their guidance can nonetheless be highly influential and useful, and should therefore not be downgraded or ignored based on considerations of clarity—which raises questions about the alternative uses that quality appraisals of individual publications might have. Finally, legitimate variability in the perspectives that methods authors wish to emphasize, and the levels of generality at which they write about methods, makes critiquing individual publications based on the criterion of clarity a complex and potentially problematic endeavor that is beyond the scope of this paper to address. By appraising the current state of the literature at a holistic level, reviewers stand to identify important gaps in understanding that represent valuable opportunities for further methodological development.

To summarize, the principles and strategies provided here may be useful to those seeking to undertake their own systematic methods overview. Additional work is needed, however, to establish guidance that is comprehensive by comparing the experiences from conducting a variety of methods overviews on a range of methods topics. Efforts that further advance standards for systematic methods overviews have the potential to promote high-quality critical evaluations that produce conceptually clear and unified understandings of problematic methods topics, thereby accelerating the advance of research methodology.
