The National Park Service website is a great resource for learning about Presidio history. You will be amazed when you click on “collections” and learn the proud and ultimately sad saga of the Army History Museum. When the base was closed Army closed it and took many of the contents with them to Washington. However, they left thousands of photos, manuscripts and artifacts that were once displayed to the public in the hands of the National Park Service. They continue to be maintained inside the stables where the NPS leases a building from the Presidio Trust. Sadly, the true treasures of Presidio history are safe, but hidden away from public view. The NPS sometimes conducts tours of the archives and allows viewing by appointment.
It contains a useful description and a chronology of Presidio history and an update of new developments and proposals. Unfortunately, the history references listed unavailable to the public.
