Where can I get OGL reference manual online?

I even visited SGI’s site,but it’s not available online.Where can I find one,please?

Or do you have some other good materials and e-books that are suitable for a programming’s use.I’ve downloaded ‘OpenGL 1.5 spec’ and OpenGL Redbook already.But these don’t meet my needs in some situations.Thank you!
Sorry,my English is not fluent.

There you’ll find the OpenGL and WGL Manual Pages in HTML and PDF.

If it didn’t come with your compiler you can use http://msdn.microsoft.com/library/default.asp?url=/library/en-us/opengl/apxb4_82lh.asp

Programming guide also available here:

Thank you.They are good ones.
I’d like to make friends with you.
