Contra Costa County Library

All Contra Costa County Libraries will be closed on Friday, June 19 for Juneteenth. All libraries will reopen for our normal hours on Saturday, June 20.

The Library Administration building in Martinez is currently experiencing a power outage. Because our network is centralized, this outage has temporarily knocked out internet, Wi-Fi, and printing services at all library locations. Access to library accounts is also impacted. There is no estimated time for restoration.

Library branches remain open for holds pickup, browsing, and checking out books. We sincerely apologize for the inconvenience and appreciate your patience.
