Systematic Reviews: Getting Started & Timelines

Defining Roles

Librarians are often an under-used resource in the evidence synthesis process, however it is recommended that the disciplinary experts on the author team manage certain steps that require specific content-area and quantitative methods expertise. Librarians who write the search methodology section of the synthesis should be included as a co-author. Librarians who collaborate on search strategy formation and/or citation management should be acknowledged in the final publication. See Defining the Role of Authors and Contributors by The International Committee of Medical Journal Editors to learn more about the role of authors and contributors

Tasks & Timelines

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.

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.)
