Hi Gail- I changed your link to the books entry on Amazon. Unless someone knows otherwise, I think any of the 'free' copies of it floating around would be pirated and not what we'd like links to from Frog Forum.

As for the book itself, it's the standard reference manual for veterinarians who treat amphibians. It's dense and expensive, but worth taking a look at if you've got a library nearby that has a copy or if you can swing the cost.
