Welcome to the California State Library in the historic Stanley Mosk Library and Courts Building.

The State Library, older than the state itself, began with several books donated on December 22, 1849 by Colonel J.D. Stevenson. Colonel Stevenson presented the books to the State Legislature in San José to establish a state library. California was admitted to the Union on September 9, 1850, becoming the 31st state in the nation.

The State Library’s location changed several times before it found a permanent home in the Stanley Mosk Library and Courts Building, which was completed in 1928. Recent renovations of the building have brought it back to its original splendor.
