There are two primary points to remember as you are writing your literature review:
General Steps for Writing a Literature Review
Here is a general outline of steps to write a thematically organized literature review. Remember, though, that there are many ways to approach a literature review, depending on its purpose.
Specific Points to Include
More specifically, here are some points to address when writing about specific works you are reviewing. In dealing with a paper or an argument or theory, you need to assess it (clearly understand and state the claim) and analyze it (evaluate its reliability, usefulness, validity). Look for the following points as you assess and analyze papers, arguments, etc. You do not need to state them all explicitly, but keep them in mind as you write your review:
These, however, are just the points that should be addressed when writing about a specific work. It is not an outline of how to organize your writing. Your overall theme and categories within that theme should organize your writing, and the above points should be integrated into that organization. That is, rather than write something like:
Smith (2009) claims that blah, and provides evidence x to support it, and says it is probably because of blip. But Smith seems to have neglected factor b.
Jones (2011) showed that blah by doing y, which, Jones claims, means it is likely because of blot. But that methodology does not exclude other possibilities.
Johnson (2012) hypothesizes blah might be because of some other cause.
list the themes and then say how each article relates to that theme. For example:
Researchers agree that blah (Smith 2009, Jones 2011, Johnson 2012), but they do not agree on why. Smith claims it is probably due to blip, but Jones, by doing y, tries to show it is likely because of blot. Jones' methodology, however, does not exclude other possibilities. Johnson hypothesizes ...
