The San Mateo County Library is a Joint Powers Authority (JPA) and comprised of the cities of Atherton, Belmont, Brisbane, East Palo Alto, Foster City, Half Moon Bay, Millbrae, Pacifica, Portola Valley, San Carlos, Woodside, and the unincorporated areas of the county.

The County Library JPA is governed by a Board consisting of representatives from each member entity. Oversight responsibility, the ability to conduct independent financial affairs, approve budgets, sign contracts, and otherwise influence operations and account for fiscal matters is exercised by the San Mateo County Library Governing Board.

Property taxes pay for more than 90% of the cost to operate the County Library. Designated as a special district, the County Library is entitled to receive a small portion of the property tax paid by all property owners in the 11 member cities and the unincorporated area. Other sources of funding include private, state and federal grants, interest earnings, fines and fees, and generous gifts from individuals and the Friends of the Library. Additionally, some member cities choose to enhance local service by providing supplemental funding to support extended hours of service.

The San Mateo County Library offers an array of library services. The 12 branches are a source of books, periodicals, newspapers and information in multiple languages. The libraries provide access to computers and the Internet, music, videos, business resources, and educational research. Online databases also serve as an additional resource for library users. The County Library website provides access to a wealth of information and is accessible in each branch library or from residents’ personal computers at home, work, or school.

The San Mateo County Library also responds to the informational, educational and entertainment needs of library users by offering a broad range of programs to children and adults including author readings, lectures, films, exhibits, dance and musical performances. Other outreach services include volunteer tutoring, homework help centers, and computer training.
