In "Open and Equitable Scholarly Communications," ACRL calls for more diverse and inclusive collection development (CD) by academic libraries and archives. Meanwhile, higher education is increasingly committing to community-engaged scholarship. This study investigated the extent to which academic libraries and archives are collecting, curating, and/or preserving knowledge produced by their local public communities. Researchers administered an electronic survey to relevant listservs and conducted follow-up interviews to develop a case study of one library's efforts. Ninety of the initial 118 survey respondents (76%) indicated that their academic library intentionally collects, curates, and/or preserves materials created or owned by the local public community, with a majority working with minority or underrepresented populations in their communities. Respondents also reported working with unpublished archival material more than twice as often as nonarchival/circulating material, reflecting academia's movement toward greater inclusion of traditionally excluded voices in the scholarly record. Additional research is needed for a host of issues raised by this work, in particular the relationship between university-community collection development and student learning. Library leaders can promote university-community engagement and knowledge diversity by incorporating local community knowledge into their collection development commitments and practices and tying this work to the parent institution's strategic plan.
