A literature review can be explained as “account of what has been published on a topic by accredited scholars and researchers” (Herbst and Coldwell, 2004, p.31).
Literature review conducted as a part of an academic research must meet the following basic requirements:
1. Literature review must be directly related to project questions and objectives.
2. Literature review must contain of synthesis of results into summary about what is known and not known about the project area.
3. Literature review must identify and discuss the areas of controversy in the literature.
4. Literature review must be instrumental in identifying areas for further research.
