A literature review is a synthesis of published information on a particular research topics. The purpose is to map out what is already known about a certain subject, outline methods previously used, prevent duplication of research, and, along these lines, reveal gaps in existing literature to justify the research project.
Unlike an annotated bibliography, a literature review is thus organized around ideas/concepts, not the individual sources themselves. Each of its paragraphs stakes out a position identifying related themes/issues, research design, and conclusions in existing literature.
An annotated bibliography is a bibliography that gives a summary of each article or book. The purpose of annotations is to provide the reader with a summary and an evaluation of the source. Each summary should be a concise exposition of the source's central idea(s) and give the reader a general idea of the source's content.
The purpose of an annotated bibliography is to:
