What is Literature Review?
The literature review is a part of the paper (such as research paper, or dissertation, or the like), in which the student present the results of his or her background study of the problem. This part is very significant. It is a one of the two most significant parts of the paper (the other one is a methodology, but we are not going to discuss it within this article). This is a part allowing the readers understand the studied problem deeper, to see its origins, to get to know what aspects were being studied before, and the like. In a word, the literature review allows you to introduce the central issue of your academic paper to the readers of your paper.
The literature review also allows you to study the problem deeper. And the deeper you study the problem, the easier it becomes for you to find the solution for it.
The literature review writing presupposes reviewing several different literature sources. Sometimes it is allowed to use the online sources as well as the printed sources for composing your literature review. However, the academic printed sources are more recognized, so you had better give the preference to them.
The literature review is the first part of the paper to be performed. When you conduct the background study and fix its results within your paper, you understand the problem better, and you are able to solve it, because you get more knowledge. So, we recommend you to start writing your paper with the literature review.
