How can working across disciplinary boundaries increase digital access to, and community engagement with, audiovisual archives? This paper, co-authored by a musicologist and two librarians, argues that multifaceted transdisciplinary collaborations can support sustainable research infrastructures that themselves serve multiple purposes. We describe the creation of a bilingual open access online portal and digital archive to provide curated access to the Fonds Jean Trudel (150+ hours of audio/video, 2000+ digital objects) and propose faculty-library collaboration as a means of working within university structures to create meaningful and sustained community engagement with archives. Following Barwick (2019), who distinguishes between archivists, end users, and “knowledge holders,” where the latter are deeply embedded in the community with which an archive is associated, we argue that a musicology-library partnership has created the necessary infrastructure for the musicologist to move beyond preservation, organization, and documentation to community-oriented transmission and dissemination, or what Seeger and Chaudhuri (2015) call the “collaborative archiving of community traditions” (25). The Fonds Jean Trudel ensures the long-term preservation and accessibility of a faculty member’s research, embeds experiential learning for information students, expands multilingual and audiovisual capacity within the library’s shared Islandora-based infrastructure, and strengthens partnerships with allied memory institutions to sustain the circulation of carefully curated, human-produced knowledge (Rothman 2024). These outcomes support the mandate of the library (Lankes 2011; Kisilowska-Szurmińska et al. 2024)
