Since it has been brought up that books tend to get to get outdated. In the years I have been keeping reptiles. I have seen things come back again that went out of favor. And if you talk with breeders taht have been doing this for years. Most will tell you that things seem to work in cycles. I said this to support the fact that books make a great base for knowledge. Yes somethings go out of date or just out of the trend. But overall you cannot beat the information that is available through them. Where do you think that the majority of the people on the internet got their information? My guess is books.
