The three major books are the "red book", "blue book", and "orange book". The "Red Book" is the OpenGL Programming Guide. The "Blue Book" is the OpenGL Reference manual. The "Orange Book" is the OpenGL Shading Language.
Just to make sure we are on the same page. Are you referring to these books(?):
I wanted to clarify because all the other books were more recent so I wasn't sure if you meant the older Reference or the Super Bible when you said blue book.
Though, OpenGL.org states that you should get the SuperBible and Programming Guide so I guess there is no harm in me linking it earlier.
Question: Is the Reference manual really all that helpful still since it is for version 1.4 and OpenGL is now on 4.5?
