Systematic Reviews: Evidence Synthesis: How Librarians Can Help
Consultant or Co-Author
As you embark on your evidence synthesis project, librarians can help at either the consultant or co-author level.
Collaborating with a librarian as a:
Consultant
As a consultant, a librarian can step in at different points of your systematic review and:
- Provide background information and resources on the systematic review process
- Recommend databases, protocol registration platforms, and citation management software
- Create search alerts to ensure that new studies are found while the systematic review is in progress.
- Find existing systematic reviews and protocols to inform your own protocol development.
- Track down hard-to-find full-text articles for screening and review.
- Suggest edits for your search strategy. As a consultant, your librarian can provide up to 15 hours of support throughout the project. (These hours may vary depending on the project).
This is our most popular option and one that works best for a lot of students.
Time Constraints
Below is a detailed chart that breaks down the steps of a traditional systematic review and the librarian co-author’s potential contributions. (Please note that these time estimates may vary depending on the project, and some steps may happen concurrently.)
Co-Author
Co-authoring is a more substantial commitment, and a librarian will typically devote more than a year to partner with you on your systematic review. As a co-author, the librarian will be more hands-on and can:
- Select databases and gray literature resources
- Write the search strategy
- Translate searches to syntax of all databases
- Perform searches and export them to citation management software
- Comment on the protocol
- Perform de-duplication, or train your team on the process
- Advise on the use of article screening software
- Write a portion of the methods section specific to searching
Due time constraints, workloads, and librarian availability, the librarian has the right to decline co-authorship.
A systematic review will typically require a year or more to complete, and librarians’ availability may vary, so please plan ahead and reach out to us as early as you can.
