How Do You Review Literature From a Discipline You Do Not Know Well?

How Can You Review a Field When You Do Not Yet Know How That Field Thinks?

You need literature from another discipline, but entering an unfamiliar field creates an awkward problem: you may not yet know enough about the field to search it well, judge what you find, or even recognize what you are missing.

The difficulty is not simply unfamiliar subject matter. Disciplines can differ in terminology, preferred databases, influential journals, methodological traditions, assumptions about evidence, citation practices, and even the meanings attached to apparently familiar concepts. A search that looks thorough from the perspective of your own discipline can therefore have substantial blind spots.

The goal is not to become an expert in the other discipline before you can review it. You need enough disciplinary orientation to search intelligently, interpret cautiously, and know which conclusions your current understanding can and cannot support.

Orient Yourself Before You Try to Review the Literature

Treat the First Stage as Disciplinary Orientation, Not Evidence Collection

Your first search is partly a search for the field itself

Researchers often approach an unfamiliar discipline with a question already expressed in the language of their home field. That is a reasonable starting point, but it can become a search constraint. The other discipline may describe the same phenomenon using different terminology, divide the problem into different constructs, or study only part of what you regard as a single concept.

This problem is documented in multidisciplinary information retrieval. Relevant literature can be difficult to retrieve when disciplines use different terms, units, or related but non-identical concepts. That means poor retrieval is not always evidence that little research exists. Sometimes you have simply asked the database a question in a language the field does not commonly use.

Early searching should therefore be exploratory. Pay attention to recurring terminology in titles, abstracts, keywords, subject headings, review articles, and the language used by influential authors. Build a working vocabulary as you proceed. If the terminology itself is becoming the main obstacle, first establish how researchers in the unfamiliar field describe the concepts you are searching for.

Find the field's evidence ecosystem

A familiar multidisciplinary database can help you enter a field, but it should not automatically define the boundaries of your review. Disciplines differ in where scholarship is indexed and disseminated. Relevant work may be concentrated in specialist bibliographic databases, particular journals, conference proceedings, books, repositories, or other field-specific sources.

Empirical work on interdisciplinary searching has found value in combining general bibliographic databases with specialist databases and supplementary sources rather than expecting one source to retrieve the entire relevant literature. The appropriate combination depends on the discipline and the purpose of the review.

Before attempting a comprehensive search, identify the databases and publication venues that researchers in that discipline actually use. A database you know well may still be useful, but familiarity is not a good reason to assume disciplinary coverage.

Use orientation sources to build a map, not to outsource your interpretation

Recent review articles, handbooks, authoritative reference works, major position papers, and well-cited papers can help you see how a field organizes itself. Look for recurring theories, constructs, authors, debates, methods, journals, and references. At this stage, you are constructing a provisional map.

Do not confuse an orientation source with the field itself. A review article reflects a scope, method, date range, and set of inclusion decisions. A handbook reflects editorial choices. A highly cited article may be historically important without representing current consensus. Use these sources to discover the landscape, then follow important claims and citations back to the underlying literature.

Backward reference checking and forward citation searching are particularly useful when terminology is unstable or unfamiliar because citation relationships do not depend entirely on your ability to anticipate the correct keywords. Current evidence-synthesis guidance recommends citation searching as a supplementary technique, and citation searches that reveal many additional relevant records can signal that an original database search needs revision.

If you repeatedly encounter older works that appear to anchor theories, methods, or debates, investigate whether those papers are genuinely foundational and why later researchers continue to cite them.

Search iteratively rather than pretending you knew the vocabulary from the beginning

In an unfamiliar field, the first search strategy is rarely your best search strategy. Early results teach you new terms. Those terms reveal new authors and journals. Those papers expose additional subject headings, theories, methods, and competing terminology. Each discovery can improve the next search.

Keep a record of these iterations if the review is intended to be reproducible. Search transparency matters even when the process is exploratory at first. For formal evidence syntheses, the eventual search should meet the methodological and reporting requirements appropriate to that type of review.

Do not assume familiar words carry familiar concepts

Cross-disciplinary reading becomes especially risky when a term looks familiar. You may read a word such as engagement, resilience, validity, literacy, intelligence, adoption, or performance and instinctively supply the definition used in your own literature. The unfamiliar discipline may operationalize it differently, locate it within another theoretical tradition, or use the same label for a narrower or broader construct.

Before combining apparently similar findings, check whether the underlying concept is actually being defined and measured in comparable ways across disciplines. Conversely, do not assume two studies address different phenomena simply because they use different labels. Cross-disciplinary searching sometimes requires recognizing conceptual relationships beneath different terminology.

Learn how the discipline makes knowledge claims

A literature review requires more than locating papers. You also have to interpret what those papers can reasonably establish.

Disciplines may differ in the research questions they prioritize, accepted study designs, forms of evidence, conventions for argument, common analytical techniques, expectations for measurement, and criteria used to discuss rigor or validity. Even within one discipline, subfields and methodological traditions may disagree.

For that reason, avoid treating the standards of your home discipline as a universal appraisal template. A study should not be judged weak merely because it does not resemble the dominant research design in your own field. At the same time, disciplinary difference is not a reason to suspend critical appraisal. The task is to determine which quality criteria are appropriate to the kind of knowledge claim being made.

Separate what the paper says from what you think it means

While reading unfamiliar literature, keep three questions distinct: What do the authors explicitly claim? What evidence do they provide for that claim? How are you interpreting its relevance to your own research problem?

This separation helps prevent a subtle form of disciplinary translation error. You may correctly understand the findings but incorrectly translate their significance into the assumptions of your own field. When an interpretation materially affects your argument and you remain uncertain about the disciplinary context, consultation with someone who works in that area may be more efficient than another afternoon of increasingly creative database searching.

Your goal is informed interpretation, not instant disciplinary expertise

Interdisciplinary research can involve integrating concepts, theories, methods, data, or perspectives from more than one body of specialized knowledge. That integration requires some understanding of what is being brought together. It does not require every researcher to acquire the same depth of expertise in every contributing discipline.

The appropriate depth of orientation depends on what you are doing with the literature. If another field merely provides background context, modest orientation may be sufficient. If a central theoretical claim, measurement decision, or methodological choice depends on that literature, the threshold should be much higher. In some cases, having a researcher from that discipline review your interpretation is an important safeguard rather than an admission that you failed to read enough.

Match the Depth of Your Review to How Much You Depend on the Other Field

You do not need the same level of disciplinary immersion for every project. What matters is how much argumentative weight the unfamiliar literature will carry.

As the unfamiliar literature becomes more central to your research, your responsibility to represent its disciplinary context also increases. The final challenge is not merely collecting studies from several fields. It is bringing those literatures into conversation without making their differences disappear.
