Chapter two is usually the longest chapter in a final year project, and honestly it is also the one where students lose marks without even realizing it. The problem is rarely that you do not have enough sources. It is that most chapter twos read like a list of summaries stapled together, one author after another, with no real conversation happening between them. A literature review should feel like you are walking your reader through what is known, what people disagree on, and what is still missing, not just reporting what each writer said.
A summary tells you what one source says. A review tells you how several sources relate to each other. If your chapter two reads like "Author A said this. Author B said this. Author C said this," one after another with nothing connecting them, then what you have is a summary, not a review. What a proper review does instead is group sources by theme and discuss how they agree, disagree, or build on one another.
The most reader friendly way to organize chapter two is by theme rather than by author. Look at your research questions and figure out the two or three major sub topics your literature naturally falls into, then build a section around each one. Within each themed section, bring several authors in together and compare what they found, instead of addressing them one at a time in separate little paragraphs.
Say your project is about employee turnover in the banking sector. Your themes might be causes of turnover, effects of turnover on organizational performance, and existing strategies for retention. Under causes of turnover, you would discuss what several different studies found, noting where they agree and where they differ, maybe because they studied different regions or different company sizes.
Most Nigerian university formats also expect a conceptual framework, where you explain your key concepts and how they relate to your study, and a theoretical framework, where you pick one or more established theories to support your research. Choose a theory that genuinely fits your topic, not just the most popular one you have seen in other people's projects. Explain briefly why that theory applies to your specific study, not just what the theory says in general terms.
This is where you talk about actual studies similar to yours, ideally ones that used comparable methods or covered related contexts. For each key study, mention briefly what they studied, how they studied it, and what they found. Then, and this part matters a lot, point out the gap. Maybe their study covered a different location, a different time period, or a different sample size than yours. This gap is what justifies your own study, and it should connect straight back to your problem statement from chapter one.
There is no fixed number, but most solid literature reviews at the undergraduate level pull from somewhere between thirty and sixty sources across the whole chapter, leaning more toward recent publications, ideally within the last five to ten years, along with a smaller number of older foundational sources if they are still relevant to your theory.
Because chapter two involves so much reading and note taking, it is also the chapter most prone to accidental plagiarism, where you copy a sentence almost word for word while taking notes and forget to rewrite it properly later. Always paraphrase in your own words and cite where it is due, and check out our separate guide on what actually counts as plagiarism in a Nigerian university project if you are not sure where the line sits.
Organizing by author instead of by theme, which reads as a list rather than a review
Summarizing sources without comparing or connecting them to each other
Choosing a theoretical framework that does not actually fit the study
Leaving out the research gap that justifies your own study
Leaning too heavily on outdated sources when newer ones exist
A well organized chapter two makes your entire project stronger, because it shows your supervisor you actually understand the wider research, not just your own small piece of it. If pulling together and organizing sources feels like too much, my team at ProjectPal can help you build a properly synthesized literature review around your topic.
