Within the research context, a literature review plays a crucial role in identifying the state-of-the-art, enriching the broader ongoing scholarly dialogue, highlighting gaps in the existing literature, sharpening the research problem, refining research approaches and methodologies, and overall increasing the credibility of the research study. The main sources of literature review include primary, secondary, and tertiary sources available online or in print copies. While internet offers many advantages there are also disadvantages, the main ones being information overload and fake information.
