A literature review is a critical analysis of published sources, or literature, on a particular topic.It is an assessment of the literature and provides a summary, classification, comparison and evaluation.
Provide the reader with strong “umbrella” sentences at beginnings of paragraphs, “signposts” throughout, and brief “so what” summary sentences at intermediate points in the review to aid in understanding comparisons and analyses.
In the conclusion, you should: Summarize major contributions of significant studies and articles to the body of knowledge under review, maintaining the focus established in the introduction.
A review may be a self-contained unit — an end in itself — or a preface to and rationale for engaging in primary research.
A review is a required part of grant and research proposals and often a chapter in theses and dissertations.
The literature review is generally in the format of a standard essay made up of three components: an introduction, a body and a conclusion.
It is not a list like an annotated bibliography in which a summary of each source is listed one by one.
You don’t need to cut each piece by yourself from scratch.
Rather, you can take the pieces that other researchers have “cut” and put them together to build a framework on which to hang your own “books”—that is, your own study methods, results, and conclusions.
If you use any of these free literature reviews as source material for your own work, then remember to reference them correctly.
The format of a review of literature may vary from discipline to discipline and from assignment to assignment.
