How to Write a Literature Review, and Where to Find the Sources

Most guides on how to write a literature review jump straight to structure and synthesis, but the step that actually eats the most time is finding and organising the sources in the first place, and it is also the step most guides skip over. Checking CrossRef, Semantic Scholar, Google Scholar and a couple of subject databases separately, then manually deduplicating what turns up, easily burns an afternoon before a single sentence gets written. This free literature finder for a literature review tool searches CrossRef and Semantic Scholar in one request, merges and deduplicates the results, and shows citation counts and open access flags right on each result so you can prioritise what to read first. Filter by year range, sort by most cited or newest, and click Cite This Paper to generate a ready citation in Harvard, APA, MLA, Chicago, IEEE, OSCOLA or Vancouver style. Pro Mode adds a minimum citations filter, an open access only filter, company filings from SEC EDGAR, more results per search, and CSV export.

1Writing a Literature Review, Step by Step

Define your scope before you search anything, a focused question like the relationship between sleep and academic performance in university students between 2015 and 2026 produces a far more usable review than a vague topic covering an entire field. Once you search and screen your sources, organise your notes by recurring theme rather than one paragraph per source, since a literature review that just summarises each paper in turn reads as a list, not an argument. The synthesis stage is where the actual writing happens, showing how the sources agree, disagree, or leave a question unanswered, which is the part that demonstrates you understand the field rather than just having read about it.

2Simple vs Pro, What Each Mode Includes

3Why a DOI Actually Matters for Your Citations

Every result includes a DOI where one exists, and it is worth knowing what that number actually does. Crossref, the non profit behind most academic DOIs, was founded in January 2000, not by a university or a government body but by twelve competing publishers, including Elsevier, Wiley, Springer, Nature and Oxford University Press, who had a shared, practical problem, a fact documented on Crossref's own history page. Reference links between journals kept breaking as websites changed, and no publisher wanted to sign hundreds of individual linking agreements with its competitors just to keep citations working. The system that resulted, first demonstrated at the Frankfurt Book Fair in 1999, assigns each paper a permanent identifier that keeps pointing to the current location of the work even after the URL changes, which is exactly why citing a source by its DOI is more reliable than citing it by a web address that could move or disappear.
