Overall, the paper summarizes the current state of knowledge of the topic.
It creates an understanding of the topic for the reader by discussing the findings presented in recent research papers. Instead, a review paper synthesizes the results from several primary literature papers to produce a coherent argument about a topic or focused description of a field.
Before embarking on writing your literature review, take in as much information as possible. Most references might end up becoming more useful than others.
Moreover, you might notice patterns between various sources, and some sources may allude to other sources of possible interest.
Scientists commonly use reviews to communicate with each other and the general public.
There are a wide variety of review styles from ones aimed at a general audience (e.g., Scientific American) to those directed at biologists within a particular subdiscipline (e.g., Annual Review of Physiology). Thus, a large focus of your paper should be a description of the data that support or refute that point of view.
Even though published books can be helpful, peer-reviewed articles are mostly considered to be the 'gold standard' of scientific research.
Go through titles and abstracts, choose and obtain articles, and then save your searches as required. The notes should incorporate anything that will be useful in advancing your thinking on the subject and in assisting you to write the literature review (like ideas, or page numbers that index vital information).
A literature review can be composed using various styles.
They may differ in the way previous research is evaluated and also the way in which the review is organized.
