Where can I find info on LightMapping ?

Where can I find decent info on Lightmapping.
I’m experimenting with OpenGl and found
surprised that it only supports “8” Lights.
That’s really not enough.
So searching the web I found out a bit of the
Lightmapping trick,Used in the Quake Trilogy.
Well I want to know all about this Subject, and apply it to OpenGL.
so I’m looking for links,faqs,tuts,pdfs, etc.

Look in the Super Bible at www.itknowledge.com/reference/archive/1571690735/ewtoc.html

I can’t think of many situations that would require more than 8 lights per object. If you can, after drawing an object with the 8 lights configured one way, change the 8 lights, then draw the next object.
I too thought 8 lights was restrictive, until I came across this idea.
