How to Write a Literature Review for a UK Dissertation (Step-by-Step Guide)

1. What is a Literature Review?

A literature review is a critical, analytical survey of existing research relevant to your topic. It is not simply a summary of what other academics have written. Instead, it demonstrates that you understand the existing body of knowledge, can evaluate its strengths and limitations, and can identify gaps that your own research aims to address.

In a standard UK undergraduate or master's dissertation, the literature review typically accounts for 20–30% of the total word count and can be the single most differentiating chapter between a 2:1 and a First-Class result.

2. What UK Markers Are Looking For

UK university markers use marking rubrics that reward the following qualities:

• Critical engagement — questioning and evaluating sources, not just describing them
• Synthesis — weaving together multiple sources to form an argument, not listing them one by one
• Identification of a research gap — showing why your study is needed
• Logical structure — themes, debates, and chronological development organised coherently
• Consistent Harvard or APA referencing — zero errors

3. Step 1: Searching for Academic Sources

Quality sources are the foundation of a great literature review. Use peer-reviewed academic journals as your primary source type. The following databases are available through most UK university libraries:

• JSTOR — humanities and social sciences
• PubMed / MEDLINE — health and medicine
• Web of Science — natural sciences and engineering
• Google Scholar — broad academic search (use to find sources, then access via your library)
• SCOPUS — cross-disciplinary, great for business and science

Aim for sources published within the last 10 years, unless a foundational older study is essential to your topic (e.g., Piaget's developmental stages for education dissertations).

4. Step 2: Reading and Note-Taking

Do not read every paper you find cover-to-cover. Use a three-pass approach:

1. First pass (5 mins): Read the title, abstract, and conclusions. Is this paper relevant?
2. Second pass (15 mins): Read the introduction, headings, and key figures/tables. Understand the argument.
3. Third pass (30–60 mins): Read the full paper critically. Note methodology, findings, and limitations.

Keep a literature matrix — a spreadsheet with columns for: Author/Year, Key Argument, Methodology, Findings, Limitations, and Relevance to Your Study. This becomes your map when you start writing.

5. Step 3: Identifying Themes and Gaps

Once you have read your sources, look for recurring themes, debates, and contradictions across the literature. For example:

• Do researchers disagree on the definition of a key concept?
• Has the consensus changed over time?
• Are there population groups or contexts that have not been studied?
• Is there a dominant methodological approach with known limitations?

These themes become your subheadings in the literature review, and the gaps you identify become the justification for your own research.

6. Step 4: Writing the Structure

A well-structured literature review follows this framework:

7. Step 5: Critical Analysis vs. Description

8. Step 6: Synthesis — The Key to a First

Synthesis is the art of weaving multiple sources together into a single analytical point. Instead of dedicating one paragraph to each author, you group authors by what they argue. Use synthesis language to connect them:

• "Consistent with…" / "In agreement with…"
• "In contrast to this, however…"
• "Building on Smith's (2019) framework, Jones (2021) further argues…"
• "Despite widespread consensus, a minority position holds that…"
• "This body of evidence collectively suggests…"

9. Harvard Referencing in Your Literature Review

Every claim you make from another source must be cited using in-text citations. For Harvard referencing (the most common UK standard), the format is:

10. Common Mistakes to Avoid

• Listing sources one by one without synthesising them
• Using only one or two sources per paragraph
• Relying on textbooks instead of peer-reviewed journal articles
• Failing to link the literature review to your own research questions
• Missing publication dates or page numbers in references
• Using Wikipedia or non-academic websites as sources
