A small result set does not necessarily mean your literature search is too narrow. Learn how to detect when restrictions, missing terminology, or excessive concept blocks are causing relevant studies to disappear.

Peer review can be useful when evaluating research, but restricting a literature search to peer-reviewed publications can exclude relevant evidence. Learn when broader searching matters and how to decide what should ultimately be included.

A literature search is difficult to reproduce if you record only the keywords or database names. Learn what to save while searching so the strategy can later be reported, checked, updated, and rerun.

Google Scholar and Google search different information environments. Learn when Google Scholar is better for scholarly literature, when regular Google is more useful, and how researchers can use both strategically.
Read Guide →
Google Scholar is an excellent scholarly discovery tool, but whether it is enough depends on the purpose and rigor of your literature review. Learn when to use it alone, when to supplement it, and why search coverage matters more than the number of databases searched.

Your university library's main search box can be an excellent starting point for finding books, articles, and other resources, but it does not necessarily search everything your library provides. Learn when discovery systems are useful and when individual databases are the better choice.

Preprint servers can reveal recent research before journal publication, but preprints have usually not completed formal peer review. Learn when searching them adds value and how to use their findings responsibly.
Read Guide →
Theses and dissertations can reveal detailed studies, emerging research, negative or unpublished findings, and extensive references that journal databases may miss. Whether you should search them depends on your research question and review methodology.

Conference proceedings can contain important research that journal searches miss, particularly in conference-oriented and rapidly developing fields. Learn when to search them, where to look, and how to handle conference papers and abstracts responsibly.

Important evidence does not always appear in academic journals. Learn where to find government reports, policy documents, official statistics, technical reports, and other nonjournal research and how to evaluate what you find.

Parentheses tell a database which search terms belong together before different parts of a query are combined. They become especially important when AND and OR appear in the same search because missing or misplaced parentheses can change which records are retrieved.

Translating a search strategy means preserving its concepts and retrieval logic while adapting controlled vocabulary, fields, operators, and syntax for another database. It is not a copy-and-paste exercise.
Read Guide →
A search strategy should evolve as you learn how the literature is described, but refinement can quietly change what the search means. Learn how to improve terminology, fields, operators, and database-specific syntax while keeping the underlying research question stable.

There is always another synonym, spelling variant, acronym, or related expression you could add to a database search. The useful stopping point comes when additional terms no longer meaningfully improve retrieval of relevant literature.

You do not need to repeat the same literature searches every week to stay current. Build a monitoring system using saved searches, database alerts, citation alerts, journal notifications, and a short routine for reviewing what arrives.
Read Guide →
There is no universal number of years that makes research “current.” The right time frame depends on what you are studying, how quickly the field changes, and what role each source plays in your argument.
Read Guide →
A literature review should represent the relevant state of knowledge, not simply maximize the percentage of recent citations. Recent research matters, but older foundational and still-relevant studies may be equally necessary.
Read Guide →
A major review can give you a strong starting point, but its publication date does not tell you where its evidence ends. Find its last search date, understand how it searched, then systematically retrieve the research that appeared afterward.

Keeping up with a research field does not mean reading every paper it produces. A sustainable system monitors several useful signals, screens new research quickly, and reserves close reading for work that could actually change what you know or do.
Read Guide →
Researchers, journals, and topics provide different routes to new research. Following topics usually gives the broadest coverage, while selected researchers and journals can add useful signals that topic searches may miss.
Read Guide →
A preprint can give you early access to important research, but being new does not make it important or reliable. Evaluate its relevance, methods, evidence, transparency, version history, and publication status before deciding how much attention it deserves.

Grey literature includes research and other evidence produced outside conventional academic and commercial publishing. Learn what counts as grey literature and when searching for it can materially improve a literature review.

Theses, dissertations, reports, and working papers are scattered across repositories, specialist databases, organizational websites, and search engines. Learn where to search and how to find documents that conventional journal databases may miss.
Read Guide →
Conference abstracts can reveal relevant studies before or without full publication, but their limited reporting makes them difficult to evaluate. Whether to include them depends on your review question, eligibility criteria, and intended use of the evidence.
Read Guide →
A conference abstract with no identifiable full paper should not simply disappear from your review. Trace the study carefully, seek additional information where appropriate, and decide what the abstract can support based on your review criteria and the information actually available.
