University of California Libraries

The University of California Libraries is the umbrella term for all libraries at the ten campuses of the University of California system. Each campus in the University of California system manages and operates its own libraries, while all campuses share a unified, systemwide catalog known as "UC Library Search".

Historically, each campus maintained its own library catalog and simultaneously participated in the systemwide union catalog, Melvyl. On July 27, 2021, all ten campuses went live with UC Library Search, a unified systemwide library catalog based on the Ex Libris Alma/Primo platform. As of 2019, it has 40.8 million print volumes in the combined collection throughout the University of California's ten campuses.
