California State Depository Library Program

In 1945, the California Legislature passed the Library Distribution Act (Government Code 14900 – 14912), which established the depository library program to make California state documents readily available to the citizens of the state. The California State Library is responsible for carrying out the provisions of the Act by developing and maintaining standards for depository libraries, granting depository status to libraries, and administering the depository program. Today a total of 108 libraries statewide participate in this program.
