The Historical Society of Long Beach (HSLB) was formed in 1962 with the mission to collect, preserve, and present the city’s history. Throughout the years the HSLB has occupied many locations around the city, settling at its current location in Bixby Knolls in 2007. Operations are sustained at the HSLB by grant funding, membership dues, and community fundraising through programs and events.

Collections include pamphlets and ephemera documenting the growth, industries, transportation, and social organizations of Los Angeles and greater southern California; photograph collections; thousands of books related to southern California; and numerous archival collections related to indiviuals, the citrus industry, and businesses in the Inland Empire.
