this book is the only one I know of that is specific on the genus Corallus. Nice,  but if you want information on Corallus hortulanus "Neotropical treeboas" might be a better choice.
 

A book I really liked because it gives a lot of information on this beautiful animal in his natural habitat. 
Information that can be used to improve the conditions in captivity.
 

This book has two sections; the first section (128 pages) gives a lot of general information on the husbandery. Section 2 gives reproductive data on boas and pythons. 
Highly recommended !!
