Looking for Material Tutorial

Sometime after Blender 2.3 the process to create and use materials changed. Most tuturials and the book “The Official Blender 2.3 Guide” explain the old system. Does anyone know of a nice tutorial on how to use and apply material in the current version of Blender 2.45.

Thanks.
