Library Sciences QUESTION #1568
Question 1
In research methodology for librarians, a 'systematic review' differs from a traditional literature review primarily because it:
  • Covers fewer sources to save time
  • Follows a rigorous, pre-specified, and reproducible protocol to identify, appraise, and synthesize all relevant evidence on a question✔️
  • Is conducted only for medical research
  • Relies exclusively on unpublished grey literature
Correct Answer Explanation
A systematic review follows a strict, pre-registered methodology — including comprehensive database searching, defined inclusion/exclusion criteria, quality appraisal of studies, and transparent synthesis — to minimize bias. Traditional literature reviews are less structured and more susceptible to selective reporting.
