Good reads...

The first 19 volumes of Underwater Speleology (1974-1992) are available on nsscds.org under Members-> UWS Newsletter (scroll to the bottom to select a year). Much of the history of cave diving can be found here.

I'm working on organizing/scanning/uploading the rest of the archive.

Thanks, Rod - I'm just tackling the first few volumes. There is some rich stuff there!

Down to a Sunless Sea is a good read, as Rich says. It is officially out of print but not difficult to find via Abe or other used book sellers.
