Following the charge provided by the University of California’s Direction and Oversight Committee in 2019, the Digital Preservation Strategy Working Group (DPS WG) focused Phase Two activities on identifying the steps needed to build a community of practice around digital preservation in the UC Library system with the primary goal of preparing a path for collective action in the stewardship of the content types held in common by the ten campuses and CDL. To this end, the DPS WG developed a taxonomy of digital content types to serve as the basis for a systemwide digital asset inventory, designed a comprehensive survey instrument administered through interviews with 44 individuals across all campuses and CDL, and conducted a literature review regarding relevant economic models for sustaining a digital preservation program.
