Ever heard of LibriVox? It's sort of Project Gutenburg for audiobooks. The selection is still small, but it's varied. It includes Charles Dickens, the Grimm Brothers, Descartes, James Joyce, Shakespeare, and Joel Chandler Harris.
It's always a surprise. I've listened to Alice's Adventures in Wonderland and some of the Grimm's Fairy Tales; the readers are all volunteers, and can change with each chapter. Some works are "solo recordings," and short works such as the individual fairy tale are recorded by one person. Though it can sometimes be a bit disconcerting to have the voice change with each chapter, all the readers I've heard have been good. (Surprisingly, the changing voices work for Alice...)
