"County Free Library Act" (1912) established and authorized the Los Angeles County Free Library, later to become the County of Los Angeles Public Library system of branches.
The library system, headquartered in Downey, California, is overseen by the Library Commission of 20 appointed members who report on administration, operation, and service to the County Board of Supervisors who operate County Library as a special fund department.
The mission of the library is to "provide our diverse communities with easy access to the information and knowledge they need to nurture their cultural exploration and lifelong learning." As such, the library provides many resources, including literacy services and programs for families and children.
The library system offers consumer health information under CHIPS (Consumer Health Information Program and Services).
