Different projects involve different kinds of literature reviews with different kinds and amounts of work. And, of course, the "end products" vary.

Keep in mind that a literature review defines and sets the stage for your later research. While you may take the same steps in researching your literature review, your literature review is not:
Not an annotated bibliography in which you summarize each article that you have reviewed. A lit review goes beyond basic summarizing to focus on the critical analysis of the reviewed works and their relationship to your research question.
Not a research paper where you select resources to support one side of an issue versus another. A lit review should explain and consider all sides of an argument in order to avoid bias, and areas of agreement and disagreement should be highlighted.
