Since there are varying sources from which you can deduce, base and derive literature review, here are some questions that can help lead you to your choice. 1. Have you clearly indicated the scope and purpose of the review? 2. Have you included a balanced coverage of what is available? 3. Have you included enough materials to show the development and limitations in this area? 4. Have you included the most recent and relevant studies? 5. Have you indicated the source of the literature by referencing accurately? 6. Have you used mostly primary sources or appropriate secondary sources?​
