Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies.
Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field.
The analytical features of a literature review might: It is important to think of knowledge in a given field as consisting of three layers.
First, there are the primary studies that researchers conduct and publish.
A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.
This is the most common form of review in the social sciences.A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories.A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem.Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse.However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].The literature review provides a description, summary and evaluation of each source.It is usually presented as a distinct section of a graduate thesis or dissertation.In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.A typical literature review comprises and evaluates different sources of research available for a particular topic that you’re writing about at college.Taking into account the fact that the formats of a literature review tend to vary.
