This section compares and contrasts published studies and identifies gaps that have not been addressed or have been unsuccessfully addressed. This section differs slightly between reviews which are part of research articles and narrative reviews.The section describes the main conclusions from analysis of all the current studies and puts forth further avenues for research.
A literature review should begin with a thorough literature search using the main keywords in relevant online databases such as Google Scholar, Pub Med, etc.
Once all the relevant literature has been gathered, it should be organized as follows: A literature review should not be a mere recounting of all the available information.
When you decide on a research topic, usually the first step you take in the direction of conducting research is learn more about the previous research published on the topic, and this eventually translates into literature review when you write your research paper.
Literature review is one of the pillars on which your research idea stands since it provides context, relevance, and background to the research problem you are exploring.
It should be a critical and analytical summary of the selected literature that guides the readers through the central theme of the research.
Body is normally used for describing the different themes under the main topic by dividing them into different subheadings.On the other hand, systematic reviews follow a well-planned methodology to qualitatively or quantitatively analyze a defined number of studies.They usually focus on a single question and have clear study objectives that are worked upon in a systematic manner.Therefore, it is one of the most critical parts of one’s research.Every research report/ thesis/research article begins with an introduction to the topic of research. The main purpose of the review is to introduce the readers to the need for conducting the said research.This section requires critical interpretation by the author such that the review adds value to existing literature.It should bring out ideas/hypotheses that can explain any discrepancies and provide solutions to existing problems.Literature reviews can be categorized as experimental and theoretical.Experimental literature review basically refers to surveying all the information available on a particular topic and critically analyzing the gaps that need to be worked upon.These studies are based on a well-defined strategy unlike narrative reviews.Systematic reviews and narrative reviews are organized slightly differently.
