How to Write a Literature Review That Actually Works

A literature review is not a summary of everything you read. It is a critical synthesis that shows how existing research relates to your own work — and where the gaps are that your study will fill.

1. Start with a clear scope

Define your research question first. Your literature review should only include sources that directly inform that question. A common mistake is casting the net too wide and ending up with a review that reads like a bibliography.

2. Organise thematically, not chronologically

Group sources by theme or argument, not by publication date. This shows your ability to synthesise ideas rather than just list them. Use subheadings to guide the reader through each theme.

3. Identify the gap

Every literature review should build toward a gap statement — the thing that existing research has not addressed, and that your study will. This is the most important sentence in your review.

4. Use primary sources

Cite the original study, not a textbook that cites it. Secondary citations weaken your credibility and can introduce errors. Use Google Scholar, Scopus, or your institution's database to find primary sources.

5. Keep your voice

Do not just quote and paraphrase. Add your own analytical commentary after each cluster of sources. Phrases like "This suggests…", "However, these studies share a limitation…", or "In contrast…" show critical thinking.
