The term "literature review" is closely related to the terms "systematic review," "scoping review," or others that describe a collection and assessment of literature for a specific topic or question.
"A systematic review is a carefully organized and structured assessment of all completed research on a specific topic. The term refers to both the process of conducting the review and the final document produced from the review process. The review establishes a specified objective and protocols to identify and evaluate all relevant primary literature, verify the validity of previous findings, and assemble and present the conclusions in a cohesive way that allows others to reproduce or confirm the findings. Performing a systematic review is less time-consuming and less expensive than conducting new studies. In addition, systematic reviews are generally more accurate than any individual study, and the results can be more widely applied (Systematic Reviews, Salem Press Encyclopedia)."
