Libraries have numerous opportunities to promote open access through subvention funds, supporting open collections, and providing access to research produced by their institutions. This workshop will guide participants in evaluating current open access initiatives, creating strategic documentation to enhance collection development for the future, and offering a roadmap for assessment and benchmarking. Librarians from the University of Colorado Boulder Libraries will share their experience in drafting a strategic plan that considers all pathways to open access, including green, hybrid, gold, and platinum options. Participants will gain a clearer understanding of data-driven methods for identifying open access needs within their organizations, how to develop SMART goals that align collection budgets with professional values, and strategies for fostering collective action around open access across their campuses.
