I keep saying this every time Delphi is mentioned, but it definitely deserves the praises:

Borland Delphi had the best and the most useful documentation/help system that I ever used - and those were times before Google or even access to Internet for many of us, so reading manuals played a huge role in learning.

I remember my Delphi manuals being quite grimy. They were always on hand and I could find something very quickly. It enabled me to get stuff done without any outside help. Windows help files were also good.
