For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text.Some disciplines require that you use information that is as current as possible." This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.
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.
The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis].
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.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?Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections.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.A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study.The goal is to deliberately document, critically evaluate, and .Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?
