- A literature review can be a compulsion for you to write if you’re writing an undergraduate dissertation. Evaluation of the existing literature on the given or choice of the topic of your dissertation is referred to as a literature review.
- It is the documentation of the state of existing literature concerning the subject or topic of your dissertation
A literature review has four main brief objectives:
- Surveying the required existing literature in the field of study, depending upon its topic.
- Synthesizing the required information of its literature into a summary, that consists of every important detail of its literature.
- Critical analysis of the information gathered by the identification of gaps with the help of current knowledge, by stating the limitations of the existing literature, and by the formulation of areas that are considered controversial for further research.
- Presenting all the gathered literature up to this point in an organized way. A literature review shows your readers that you have an in-depth grasp of your subject; and that you understand where your research fits into and adds to an existing body of agreed knowledge.
Another method of describing those four tasks that are needed to be carried out for stating a proper literature review are as follows:
- It demonstrates a familiarity with an existing knowledge body and establishing your work’s credibility along with it.
- It summarizes the prior researches in it along with stating its relationship with your project.
- It provides integration and a summary of the subject that is covered in your dissertation.
- It demonstrates how the previous works have helped you learn more about the specified topic as well as how your research picks it up and provides a new perspective to it and hence, concluding its specified gap or loophole with a solution.
