Writing a Literature Review
A literature review is a form of writing that surveys all the published research and scholarship on a particular topic (ie. journal articles, books, dissertations, conference proceedings, reports). It provides a description, summary, and critical evaluation of each work, however it is more than a simple report of facts or summary of articles. The purpose is to present an overview of significant literature published on a topic and offer new interpretations within existing ideas.
Literature reviews are written as both full length articles that present the “state of the art” on a topic, or as introductions to new original research studies.
The purpose of a literature review is to:
Literature reviews should include:
The literature review itself, however, does not present new primary scholarship.
Choosing a Topic
Reviewing the published literature is a great strategy for identifying issues of current interest to scholars and yourself. It's helpful to start with a general subject in mind and narrow down as you become more familiar with the research. The more focused the topic the easier it will be to survey all the published research.

When you first begin reviewing the literature you can scan rather than read in-depth as you compile potentially relevant sources. Reading the abstract and a quick scan of most articles can be enough to determine if it should be investigated further. Make sure to save and take careful notes of each source as you go.
When you are satisfied with searching, read each article carefully, evaluating both the main theories and evidence of each work and looking for larger themes and issues across studies.
You will likely need to return to searching at certain points to fill in knowledge or answer additional questions that come up as you read.
There are several common techniques to assist you in organizing ideas. One way is to write an annotated bibliography that briefly summarizes each article followed by a description of how it relates to your thesis or research question.
Another technique is to create a concept map, or diagram, that shows relationships between ideas in a visual way. For examples, search the web for "literature review concept map".
Like other academic writing, literature reviews have an introduction, a body section, and a conclusion.
A literature review should include:
Most literature reviews are organized around key themes or issues in the research, but they can be organized differently depending on the topic, for instance chronologically or by the research methods used.

When a literature review stands alone, it is reviewing what is known about the topic, analyzed for trends, controversial issues, and what still needs to be studied to better understand the topic at hand. A stand-alone literature review can be as short as a few pages or may be more extensive with long bibliographies for in-depth reviews.
Literature reviews can be used as part of dissertations, theses, research reports, and scholarly journal articles. They generally discuss what has been done before and how the research being introduced in this document fills a gap in the field's knowledge and why it is an important.
