I picked this book up in Smithsonian Gift Shop. It is pocket sized and has 1 page on about 220 species. Each page has a description of the snake and a good (but small) color photo. It then gives a brief blurb about average size, distribution, habitat, diet, breeding and similar species. Overall, a nice little book - well worth the money. You won't get much detail on any individual species, but there are some neat facts on the overview pages. Well worth it for someone with a basic interest in various snakes around the world -- even if just for the photos. Don't expect a lot of new info. While there are not too many details, they seem to have most of their facts right.
