There may be several different possible structures for your review. There is no one ‘correct’ way to structure a literature review; your discipline and your topic shape how the document develops. Your review could be organised in one of the following ways:
A literature review requires you to display a critical synthesis (not summary) of the information you have discovered. To synthesise information implies joining disparate information into a cohesive whole – this is the core work of any effective literature review.
Avoid presenting material from one author, followed by information from another, then from another, and so on. This ‘shopping list’ approach can unhelpful for your readers who require a more analytical approach. Instead, identify patterns across the literature to group authors or studies together. To group authors who draw similar conclusions, you can use linking words such as; additionally, again, similarly.
Due to the multitude of other writers’ voices in a literature review, your own voice has much greater potential of being drowned out. However, your own voice needs to be strong throughout the literature review; it needs to introduce and guide the reader through significant research on your topic and, as such, takes a prominent ‘hand-holding’ role in guiding the reader through the literature.
When authors disagree on a topic in the literature, linking words that indicate contrast will show the reader how you have understood their work such as; alternatively, conversely, nonetheless. At other times, you may want to qualify an author's work (specifically, usually or generally) point to an example (namely, to illustrate, to exemplify) or indicate a causal relationship (due to, resulting in, since).
Plagiarism occurs when you copy another author's ideas or words without acknowledging their source. Anything you get from a source, even if you write it in your own words, needs to have a citation or footnote.
Your literature review is based on the work of other authors, so you must be very careful to separate an author's evaluation of research from your own.
The University of Melbourne has a comprehensive website that will tell you more about plagiarism. It is highly recommended that you read this site to get a greater understanding of the University's approach to plagiarism.
Academic Skills has a brochure outlining how to use sources and avoid plagiarism.
