Check out amazon for al kinds of books, I know they have some great books on 3D thingy's.
But maybe you can better invest in DVD's you can order over the internet, like on simply3D, but that is offcourse what you like. You can also just buy tuturials on the subjects you are in need of.....that could be more effective and cheaper to than buying an whole book, that probably fills more holes then there are in need to b filled.
just my 2 cents
(and that isn't a % of 50 cents' !!)
