A literature review is a critical summary and analysis of existing research and publications on a specific topic. It explores what other scholars have written, highlighting key ideas, theories, and debates within the field.

How do I conduct a literature review?
Start by searching library databases for relevant books and journal articles. Use bibliographies and existing literature reviews to find additional sources. Reviews of books or articles can also highlight how they were received and their impact on the field. Keep a record of your searches and results so you can revisit them.
Assess each source for relevance and usefulness in answering your research question. Use different reading strategies to identify key arguments and evidence:
If a source is key, read in depth but not necessarily every page. Ask:
Record each source as you find it. Include database, search terms, and date. Use tools like RefWorks or EndNote, or note cards, and apply a proper referencing style from the start. For each source, note author, argument, key concepts, research method, and your reflections. Make clear notes on main points and perspectives and organize them by emerging themes for your review.
Present authors’ arguments in a logical order, highlighting similarities and differences. For each source:
State the research question, outline the debate, explain why the topic matters, and note any scope or limitations.
Present previous research and arguments in a logical order (by theme, chronology, theory development, sector, or methodology).
Summarise key ideas, highlight gaps, and show how your research builds on existing knowledge.
