Centers for Teaching and Learning (CTLs) have long collaborated with academic librarians, especially around the Scholarship of Teaching and Learning, but full, reciprocal partnerships are relatively rare. This exploratory, interview-based study seeks to gain insight into how participants (n=4) experienced one such partnership, focused on building institutional capacity for engagement with scoping reviews in SoTL. Our findings reveal that these types of partnerships can have distinctive influences on participating faculty members that extend beyond a single program, service, or project. These insights illuminate the challenges and opportunities long-term partnerships present to both the institutionalization of SoTL and the evolving positionality of both educational developers and librarians (and their respective units).
