The San Francisco Public Library is the public library system of the city and county of San Francisco in United States. The Main Library is located at Civic Center, at 100 Larkin Street. The library system has won several awards, such as Library Journal's Library of the Year award in 2018. The library is well-funded due to the city's dedicated Library Preservation Fund that was established by a 1994 ballot measure. The Preservation Fund was renewed twice, by ballot measures in 2007 and 2022.
