The evidence synthesis process is complex and requires not only expertise, but specific knowledge and skillsets. Temple University librarians trained in evidence synthesis methods can provide educational support or perform various steps of the review process for your team. Having a librarian on your team will give you expertise throughout the process, reliable results, and documented methods.
We expect that librarians who offer substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work will be offered co-authorship for per ICMJE recommendations http://www.icmje.org/recommendations/. For more information about librarian contributions to evidence synthesis see the citations below.*
Below is a detailed chart that breaks down the steps of a traditional systematic review and the librarian co-author’s potential contributions. Other review types may have different steps.
