Victorian Homes of San Francisco is authored by Terry Way. It has been out a few years but I only recently discovered it. It is a treasure trove of photos of the unique San Francisco style of ornamentation and is a must have reference for any one looking for insight into period exterior detailing.
A soft cover book it retails for 19.95 on Amazon, but if you don't mind buying a used copy you can pick one up for 10-12.00 on Ebay. There is not a Kindle version availale.
