looking for a link on nodes

At one time I stumbled across a very detailed page that explained nodes. If im not mistaken it was a few pages long. At that point i was not intrested but the time has come where I would like to learn how to use nodes. If any one knows the link I speak of or just a good link about nodes and how to use them, would you plz post it for me.

Thx Mux.
