Understanding the Landscape for Review of Literature

Abstract The review of literature is very much essential as it helps researchers understand the required knowledge on a specific area or topic. The review of literature always plays an important role in identifying the research gaps in specific fields, emphasis on the importance of a topic, and give grounds for the significance of specific study. The purpose of a literature review is to gain the knowledge of the existing research areas of study with the help of secondary data, analyse the information and to present that knowledge in the form of a report writing. The word literature means the source of information. Research and researcher’s perspectives are different, as their research problems and problem statements are different. But it is important for every researcher to know a definite research process flowchart to work effectively and efficiently for addressing research problem effectively. Research is continuous process, searching again and again for achieving accurate results will be possible only when the researcher have a strong study of literature review. Literature review develops the ‘knowledge base’ of researcher. The literature review will give the data about the research which has been already conducted on the specific areas or topics. The literature review can not be repeated unless there is change in demographics, new technical development in that area and change in testing tools. The literature review synthesizes the information from multiple resources to address the research problem.
