Introduction
The University of Prince Edward Island (UPEI) formally introduced knowledge synthesis (KS) services in 2021. The main aims of this study were to determine usage of the KS service, involvement of librarians in these publications, and if librarian involvement demonstrates a trend with citation counts.

Methods
A search in OpenAlex was conducted to identify English-language systematic and scoping reviews published by University-affiliated authors. No publication date filter was used. Data extraction was completed by the authors.

Results
Sixty-eight KS publications between 2007 - 2025 were found. Thirty-eight publications included librarian involvement, 8 of which were UPEI librarians. The Faculty of Science engaged librarians the most. The highest average citation counts occurred on KS with librarians as consultants (n=320 citations). A negative binomial regression model revealed inconclusive results for the individual effects of librarian involvement and open licensing on citation counts. However, their combination showed a statistically significant synergistic effect, with co-occurrence of both factors associated with substantially increased citations.

Discussion
UPEI authors have been conducting KS projects since 2007 and while the majority of KS included librarians, only 21% were UPEI librarians, indicating that librarians at partner institutions are essential in supporting UPEI authors. Overall, librarian involvement was represented mostly as coauthors but interestingly, publications with librarians as consultants had the highest average number of citations even though it only represented 6% of the KS. An identified area of opportunity is Atlantic Veterinary College, where only 28% of KS publications include librarian involvement.
