There is very few published books that specificlly take on the topic of Just Boa Constrictors, but there is a plethra of information in general books on reptiles or snake. Most of the larger breeders that have websites have all kinds of information posted on thier sites. I have some on Mine, Gus has great information on his, Jeff Ronne has breeding info on his, Pro Exotics has a nice FAQ section on their website and Hermann the Germann has some of the best Locality and care information on the net posted onto his. The Syntax might be off on a word or two here and there but that is because of the German/English translation but the information is great. I am sure that there are many others who have great infomative sites but I don't know them all LOL. Back issues of reptiles magazines. Nov 1996 was a great Boa Constrictor issue, sadly reptiles does not seem to place much attention to the world of Boas anymore which to me is unexplainable but I guess the monthly bug articles are more important, When did they place bugs in the reptile family anyway, I must have missed the workshop on that one?
I can't say for sure on Jeff's video as I have never seen it, but I do know that every time someone quotes the 105 POS time frame that the credit goes to Jeff for doing that research. Check out his breeding article posted on his website. It is from the Nov 1996 issue of Reptiles magazine. It is there that he coined the POS term the dates and the most of the breeding information that is used today on a regular basis. So regardless of what other may claim, he put that info out there before many of them ever thought of breeding Boas! I see many claiming that information to be their results of their own study, while it may be true that many have duplicated and confirmed his info, he was there to publish it first (but I and getting side tracked on an issue).
I have found that field guides from different Boa localities is a great source of information. Although these field guides give only the basics about the bosa that live there, they do provided information on climate conditions, year round highs and lows, rain fall and humidity, elevations, prey and seasonal light cycles. Putting the information that this is where the boas live and this is what their natrual enviorment is like goes a long ways to telling you how to keep your snakes.
If you have any question and can't find the information you need, let me know and I will try to guide you to the right direction.
