I was in college 95-99 and this was THE source for this type of information. As soon as you asked a question you'd be told "beej". The specific assignment that I remember we had was to write a web server, in C, I think on Solaris boxes back then. All of what is now in Section 5 was the perfect source here. The only alternative at the time I recall was manpages which are good, but don't explain it as well especially how the calls relate to each other. We didn't have IPv6 to deal with then but the IP block/ordering stuff was also quite useful.
