1. First read the “Systematic Review Overviews” and “Planning” section of this Guide to get familiar with the systematic reviews, and decide whether SR is the best type of review to answer your research question. It is important to know the difference between a Systematic Review and a literature review conducted in systematic ways. If you are interested in the latter, read the how-to books on literature reviews featured in here.
2. Find the systematic reviews in your field (or on your topic), and read them.
3. Read the books on how-to’s of SRs such as “Systematic Reviews in the Social Sciences”
4. Check out SR Registries to see if there are any ongoing SR projects. If you are conducting a Scoping Review, consider registering your Scoping Review at Open Science Framework. PROSPERO does not accept scoping reviews.
5. Schedule a meeting with your liaison librarian to discuss your search strategy.
