Building capacity for librarian support and addressing collaboration challenges by formalizing library systematic review services.

The two-tiered service model developed for advisory consultation and collaboration provides a framework for supporting systematic review activities that other libraries can adapt to meet their own needs. Librarian autonomy in deciding whether to collaborate on reviews based on defined and explicit considerations was crucial for maximizing librarians' time and expertise and for promoting higher quality research. Monitoring service usage will be imperative for managing existing and future librarian workload. These data and tracking of research outputs from librarian collaborations may also be used to advocate for new librarian positions.
