The Reproductive Husbandry of Pythons and Boas. Richard A. Ross M.D., M.P.H. Gerald Marzec Published by the Institute for Herpetological research, Stanford, California. Picked up this little gem at a used book store. Looked interesting, so for $6 I thought I would give it a try. Well worth the money, even if you don't breed snakes (and doubly so if you want to start.) It is very comprehensive, and covers breeding every step of the way, from assessing and pairing adults for breeding, through copulation, gestation, and incubation, including various methods for incubation, problems any breeder might encounter (egg retention, etc.) and care of neonates. Also contains profiles and records on most genera and species, including those with no documented or successful captive breeding. Overall, a pretty good resource for those considering breeding, or those just interested in reading about it.
