I read an article in CoinWorld Feb 6,2006 about this website. The site is an online bibliography for books about sunken treasure. I checked the site and found it to be quite interesting and easy to use. There's a nice search feature so you don't have to dig through the listings to find things you're interested in.

The site is created and maintained by Dave Crooks who is a collector of references about sunken treasure. A very nice job.
