The foundation of the University of California libraries digital preservation program, the Digital Preservation Repository (DPR) serves the stewardship mission of the UC libraries by providing a single shared solution for the preservation, management, and controlled dissemination of digital collections that support research, teaching, and learning. The repository provides a set of self-service interfaces that the libraries use to deposit and manage digital objects, relieving individual libraries of the burden of creating and maintaining custom digital repositories. The services and storage are based at the California Digital Library (CDL).
