California Digital Library
CDL
Supporting the University of California community's pursuit of scholarship and the University's public service mission.
The California Digital Library (CDL) was founded by the University of California in 1997 to forge a better system for scholarly information management and improved support for teaching and research. In collaboration with the ten University of California libraries and other partners, CDL has assembled one of the world's largest digital research libraries. CDL facilitates the licensing of online materials, develops shared services used throughout the UC system, and explores how services such as digital curation, scholarly publishing, archiving, and preservation support research throughout the information lifecycle.
