Global Illumination Compendium
July 2001 - Philip Dutré
This is a collection of formulas and algorithms useful when performing lighting calculations, e.g. in ray tracing or radiosity lighting.
Virtualized OpenGL Light Sources for Efficient Multi-Light Source Lighting
This article describes how to do hardware accelerated lighting in scenes with more than 8 light sources. This is possible by enabling only the lightsources that actually does any difference in the lighting.
April 2001 - Hugo Elias
This article gives a very good description of radiosity lighting and how to implement it. It also mentions a couple of optimizations that can be made to speed up the algorithm.
An Investigation Into Lighting in Computer Graphics
2002 - Peder Herborg, Jacob Mortensen, Gorm Lai, Kasper Fauerby, Carsten Kjaer
This articles discusses the implementation of raytracing, radiosity, and photonmapping.

Feb, 2005 - Michael Bunnell
This article shows how global illumination can be done on the GPU.
