In the summer of 2025, a team of three librarians ran a six-week online LIS Research Accelerator program that led participants through the research process, from project ideation to dissemination. While this program was initially designed to support participants’ developing their research skills, it was also intended to be a community-building mentorship program. Participants were provided mentorship support by the facilitators, and the sessions were designed to encourage peer-to-peer engagement. This presentation will focus on the engagement and mentorship aspects of the program and will argue the importance of community building in online programs, particularly those designed for early-career mentorship.
