The Bernal Heights branch of the San Francisco Public Library system, which has 27 branches in total, has always been in a single location.
A "library deposit station" was established in 1920 at 303 Cortland Avenue. As the neighborhood and library grew, it was moved, in 1936, to 324 Cortland. The one floor branch library at 500 Cortland, was the 21st in the system and built on the site of the original Bernal School at a cost of $94,600.
