Shorock.com is (for now, anyway) mostly photo albums that were created by Don Shorock. Don passed away in 2010.
His son, Tom, is slowly working to organize the better parts of that material. Some links will continue to break, some may re-appear.
If you're really missing something from shorock.com, send a message to email@example.com. Glad to hear from you.
I might also suggest finding material in the Wayback Machine archive, if the link you're looking for is broken.
