I am thinking of buying the blue book since I normally am not around a computer with an internet connection while I work. I saw on half.com and a couple other places talk of a blue book for Version 2.0 http://product.half.ebay.com/Opengl-...16610QQtgZinfo but everywhere I look they have none of these. Is there a reason the newest version I can find for sale is for 1.4? Thanks for your help!
