Dr. Nirmal Kumar Swain delivered a lecture to research students on conducting literature searches. He discussed that a literature search is a well-organized search of all published literature on a desired topic. It is important to carry out a literature search to review existing theories and research findings, identify gaps, and find potential research methods. Dr. Swain outlined the steps to conducting an effective literature search, including preparing by doing background reading, identifying search terms from the research title, searching relevant resources like databases and repositories, and using effective search techniques before collating the results.
