Library History

Founded in 1913 as the second branch of the Los Angeles County Free Library, the San Dimas Library was originally located in the back of Fairbank’s Drug Store. Subsequently, it moved to a storefront location on Bonita Avenue. The present building, located in the San Dimas Civic Center, was dedicated in 1971.
