Lasting Impact: Sustainability of Disciplinary Repositories “offers a quick environmental scan of the repository landscape and then focuses on disciplinary repositories—those subject-based, often researcher-initiated loci for research information. Seven of these repositories are profiled, with a focus on their varied business models. The report concludes with a discussion of sustainability, including funding models, factors that contribute to a repository’s success, and ways to bring in additional revenue. It is intended to help librarians support researchers in accessing and disseminating research information.”
