Gov. Code, § 14905

To be classified as a “complete depository” or as a “selective depository” of physical materials, a library must contract with the California State Library to provide adequate facilities for the storage and use of the publications, and must agree to render reasonable service without charge to qualified patrons in the use of the publications. A library designated as a “complete depository” shall be sent one copy of every state publication in a physical format, while a library designated as a “selective depository” shall be sent one copy of each publication existing in physical format from only the subset of issuing agencies the library selected or one copy of each publication existing in physical format of the publication type selected by the library.
