visual encyclopedia?

I'm looking for a huge visual encyclopedia of mainly snakes, something similar to Smithsonian's Animal. An almost all inclusive visual encyclopedia of all the worlds snaks. Price isn't a factor. I want the best available. What are your opinions

The Atlas of The Snake of the world by John Coborn is a must have.. is and old position 1991 but I still believe the best up to date.. Problem is ... is expansive... on amazon price range form 83-309$

I by myself Using The Mini-Atlas of Snakes of the World by the same author... You Can Grab "NEW" on the Amazon for 43 $

Hope This Helps :gj::gj::gj:
