The David Rumsey Collection, the fantastic online resource for digitized historic maps, has recently scanned and made available a 1905 Sanborn fire insurance atlas of the City of San Francisco. The atlas is very valuable resource for many reasons, thogh specifically beccause it dates to just months before the historic 1906 earthquake and fire that destroyed a large portion of the city.
The original atlas belongs to the San Francisco Public Library's San Francisco History Center. You can read more about the atlas on the David Rumsey Collection blog and view the pages themselves at the David Rumsey Collection site.
