By no means a new site, but frequently updated, this is one to bookmark if you have any interest in the history of San Francisco. Their online exhibits feature articles, images, and a cornucopia of archival materials relating to the 1849 California gold rush, the great earthquake and fire of 1906, the 1989 earthquake, the construction of the Golden Gate and Bay Bridges, San Francisco World War II events, San Francisco rock music of the mid-to-late 1960s, and much more. A general subject index to all of the online holdings is offered as well as a chronological and biographical listing of these materials.
