Although this species has been increasing in popularity and bred by many hobbyists for over 10 years there are no specfic books that I am aware of Candace. Word of mouth is still the best learning medium and there are few websites dedicated to them solely.
http://www.roborovskii.com has some good informaton, although sadly has not been updated for some time, but really if you have any specific questions you are best to ask them on the forum and then the experienced Roborovoski breeders amongst us can hopefully answer them to your satisfaction...
