I was actually disappointed by this book.
Each chapter in this book was written by a different person, most of them highly educated academic herpetologists. There's nothing wrong with the information, except if it's become dated since publication. Unfortunately the whole book is just hard to read! The authors wrote for their own educational level; whether the rest of us can follow it or not depends on how interested we are in the material, how good of a herpetological dictionary we have, and our own educational level.
The pictures are beautiful, probably worth the cover price alone.
It's just - as a writer - I know this could have been written so all could read it. My frustration is that people, particularly young ones, would get turned off on herpetology and perhaps even on science after trying to read this book.
