California Digital Library

Consortial Abbreviation: 
Brief Description: 

The CDL was founded by the University of California in 1997 to take advantage of emerging technologies that were transforming the way digital information was being published and accessed. Since then, in collaboration with the ten UC campus libraries and other partners, CDL has assembled one of the world’s largest digital research libraries and changed the ways that faculty, students, and researchers discover and access information.  We facilitate the licensing of online materials and develop shared services used throughout the UC system. Building on the foundations of the Melvyl Catalog, CDL has developed one of the largest online library catalogs in the country and works in partnership with the UC campuses to bring the treasures of California's libraries, museums, and cultural heritage organizations to the world. We continue to explore how services such as digital curation, scholarly publishing, archiving and preservation support research throughout the information lifecycle.
