The Historical Society Museum, at 80 Chestnut Avenue houses a collection which includes vintage clothing, photos and artifacts, oral history tapes, historic school yearbooks, newspapers and maps, special exhibits, and a database for researching historical photographs. The Plymire-Schwarz Center is a restored 1905 colonial revival style house located at 519 Grand Avenue. This historic home was donated to the Historical Society who worked diligently to restore the furnishings with period-appropriate antiques.
The South San Francisco Historical Society's digital collection at California Revealed consists of audio recordings from the 1970s to 2010s. The collection includes many oral history interviews with local residents, including members of the Greek and Portuguese communities.
