The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Should I provide subheadings and other background information, such as definitions and/or a history?
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.
Historical Review Few things rest in isolation from historical precedent.
Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline.
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated.
The body of literature includes all studies that address related or identical hypotheses or research problems.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].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.

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.The unit of analysis can focus on a theoretical concept or a whole theory or framework. Problem formulation -- which topic or field is being examined and what are its component issues? Literature search -- finding materials relevant to the subject being explored. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? Should I summarize, synthesize, or critique sources by discussing a common theme or issue? Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review.If your assignment is not very specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. The bibliography or reference section of sources you've already read are also excellent entry points into your own research.
