All information on the Keystone Hotel built on 4th and Market. How many owners did it go through and a brief story on each owner? Who built the hotel? Any news articles and early pictures of the hotel? Any famous people staying at the hotel.

I'd recommend you start by looking through San Francisco city directories, till you can isolate what years the hotel was in operation. (Pre-earthquake? Post-earthquake?) Then you can start looking through newspapers and records that would be approporiate to that year. Good luck with your research!
