A literature survey, also known as a literature review, is a critical analysis of existing literature in a particular field of study. It involves systematically reviewing and evaluating a range of sources, including academic journal articles, books, conference papers, and other published materials.
The purpose of a literature survey is to identify and analyze key research themes, trends, and gaps in knowledge within a particular field of study. It can also help to highlight the theoretical frameworks, research methodologies, and key findings that have emerged from previous research.
To conduct a literature survey, researchers typically begin by identifying a research question or topic of interest. They then conduct a comprehensive search of existing literature using databases such as Google Scholar, Web of Science, or Scopus. The researchers then read and critically evaluate the sources they have gathered, taking notes on key findings and identifying areas of consensus and disagreement.
The literature survey should be organized in a clear and coherent manner, with a logical structure that reflects the key themes and trends identified in the literature. It should also include a critical analysis of the strengths and weaknesses of existing research, and identify areas where further research is needed.
Overall, a literature survey is a valuable tool for researchers, helping them to build on existing knowledge and identify gaps in the literature that can inform future research.
