Learn OpenGL with THIS book,
This review is from: OpenGL Distilled (Paperback)
OpenGL Distilled is an excellent reference for developers who are new to OpenGL. It tackles platform specifics for Windows, Mac, and Linux, and makes use of GLUT and GLU in the core text so that focus can stay heavily on OpenGL itself.
I learnt OpenGL with this book, and then progressed on to the main Programming Guide and Shader Language reference texts (the "red" and "orange" books). I still refer to this book quite often though, as it is so well written, it's often hard to beat for looking up an explanation of something.
This book covers features right up to OpenGL 2.0. It has the best explanation of how extensions work, and how easy they can be to manage, that I have seen anywhere.
