The Literature Review
Now that you got the green light to go ahead with the project, the next step is to dig into past research, and all sorts of published material, to learn as much as possible on your topic, and the best way to measure your variables.
All papers have a literature review. If the paper is exploratory, the literature review section will be thin, as no prior research has been done. This is ok and expected. If, however, the project is explanatory, the literature review might be very long, up to 50 pages, since you are trying to advance research in a field where much has been done before you.
YOU MUST ATTRIBUTE PRIOR KNOWLEDGE TO ITS RESPECTFUL AUTHOR.
Citing past research is a question of honor, but also logic. Science hinges on the values of transparency, and cooperation. Without honest attribution of other people’s contributions, who would want to work hard on a scientific project? Why give away the credit to anyone else? Attributions are clunky, and long. But they are essential to the process of scientific advancements.
Pitfalls
NOT LITERARY. A literature review is not a review of exclusively literary works, such as fiction novels, and poetry. In English, the term literature refers to almost anything that's been published, such as academic journal articles, but also non-fiction books, newspapers, and popular magazines. Literature includes fiction and non-fiction works.
NOT BOOK REVIEW. Avoid presenting the paragraphs in the order of books or articles you consulted. This is not a succession of book reviews, where you would have a paragraph for each book. Rather, you should sort out the documents, and organize them by topics. Each paragraph of the literature review should present sources that have something in common.
NOT TOO LONG. To save on space, literature reviews are often very concise. To be short, write short.
Format
Start the section with a qualification of how much knowledge exists on this topic. Mention how detailed your review of the literature will be. Explain how the literature fits into the rest of the project. State your research question.
Organize the paragraphs in order of ideas – or types of findings – you wish to discuss.
Cite the last name of the source every time you add a piece of information. Compare findings from sources in the same paragraph. They can oppose each other, or complement. It’s more than OK to have 3-4 sources cited in the same paragraph. Don’t present a series of book reviews, in the order you read them.
