Green, Johnson and Adams describe a literature review as a type of research article published in a professional peer-reviewed journal.
The purpose of a literature review is to objectively report the current knowledge on a topic and base this summary on previously published research. A literature review provides the reader with a comprehensive overview and helps place that information into perspective.
