The link that was already given to you will allow you to buy the book directly from NERD, which is owned by Kevin McCurley, who wrote that book. So it is the best way to get the money to the person who wrote it! I have not personally read it, but everyone seems to think it is a fabulous book and it does include advanced stuff including stuff about breeding.

Another book that is very highly recommended is Pythons of the World, Vol II: Ball Pythons, by the Barkers who own VPI. Here is a recent thread comparing the 2: http://www.ball-pythons.net/forums/s...ad.php?t=58994
