A frequent technique to a literature review is to begin broad and then develop more focused. Consider it an inverted triangle: First, quickly discuss the general concerns relating to your inquiry; you don't need to write much about this; just show that you understand the scope of your subject. Next, focus on one particular aspect of your topic and study it in depth using both primary and secondary sources. Finally, broaden your view again by considering other aspects of your inquiry and including them in your discussion.
Literature reviews are usually divided into three parts: (1) a brief introduction describing the state of knowledge on the topic under investigation, (2) a detailed analysis of at least five publications that deal with the same or related issues, and (3) a summary statement outlining future research needs. Although not always done in writing, a literature review often begins with a conversation between two or more people. During this conversation, they will identify relevant studies or documents that they believe might help answer the question being asked. Based on what was discussed during the conversation, these individuals can then decide which studies should be included in the final review.
In conclusion, a literature review is a useful tool for researchers to understand different perspectives on an issue while identifying gaps in existing knowledge. It is important to be aware of potential limitations when interpreting results from studies conducted by different investigators for the purpose of conducting your own review.
How to Write a Literature Review in 6 Easy Steps The first stage in the procedure is to investigate and pick a topic. As you learn more from the literature, you may modify the topic/scope of your study. Choose a topic on which you are willing to work for an extended period of time. It is important that you choose a topic that is both interesting and useful. An interesting topic will keep you engaged with the literature, while a useful topic will provide enough material to write about.
In addition to being interesting and useful, the topic should be relevant to what is known as the "field" or "subject matter" of library science. This means that your topic should relate directly to the body of knowledge produced by libraries and information scientists. If you pick a topic that is outside of this field, you will not be able to offer much new insight regarding the subject.
After you have chosen a topic, the next step is to define its scope. What parts of the subject are you going to cover with your literature review? Will it be limited to one specific area of research or study of many different topics within libraries and information sciences? Will it focus on primary or secondary sources? These are some of the questions that you need to ask yourself before starting your review.
Once you know the scope of your study, you can start looking at the literature.
A literature review is composed of various steps:
How to Write a Literature Review
A literature review should be formatted similarly to an essay, with an introduction, a middle or major body, and a conclusion. The opening should: describe your topic and set the stage for evaluating the literature; Determine your reasons (i.e., your point of view) for conducting the review; Explain how other studies on your topic are relevant to your own research; and Outline what questions you will answer through this study. The middle body should include all relevant information gathered from the selected articles that directly relates to at least one of your stated reasons for conducting the review. The conclusion should restate your original reason for conducting the review and also highlight any new insights gained from the study.
An effective literature review not only provides readers with a clear understanding of your topic, but it may also help them find related work in their fields. As such, an important part of any good review is its ability to identify gaps in the existing knowledge base. A reviewer should therefore determine whether there are any previous studies on your topic that were missed by the search strategy employed. If so, these articles should be included in the review.
Finally, a good literature review makes use of appropriate scientific sources. These can include journal articles, books, conference papers, the researchers themselves, and even academic libraries. When looking at different sources, be sure to distinguish between those that provide statistical data and those that do not.
Here's a step-by-step guide to writing a literature review:
Literature reviews, like other academic papers, must include at least three fundamental elements: an introduction or background information part; the body of the review with a discussion of sources; and, lastly, a conclusion and/or suggestions section to conclude the study. In addition, literature reviews may require a reference list section.
In general terms, literature reviews try to summarize the current knowledge on a subject by discussing studies that have been published on it. They are usually written by librarians for use by teachers and researchers when there is not enough time to conduct original studies.
A literature review should be distinguished from an annotated bibliography. Annotated bibliographies are lists of books that have been used as sources by authors conducting research or writing papers. They are useful tools for identifying important works on a subject and providing brief comments about them. Annotated bibliographies do not aim to give a complete picture of all research activity on a topic but rather to help readers identify key texts which will then be pursued further.
To answer this question, you would need to look at both experimental and observational studies (pieces of research based on actual observations rather than experiments).
