Jules,
I'm replying to everyone for those not aware of the book Cave Conservation
and Restoration. At 600 pages long and with high quality material, it is by
far the most comprehensive, complete, and up-to-date source of information
on the topic. It was published by the NSS two years ago and
I am holding in my hands about 6 pounds of Cave Conservation and
Restoration, the 2006 Edition, edited by Val Hildreth-Werker and Jim C.
Werker and published by the National Speleological Society. It is 600 pages
thick and may be purchased on-line from the NSS bookstore
