There is a web site, LibriVox, that makes audio books from public domain books and they are free to download. The range is wide, from Aesop to Emile Zola. LINK
Nice to have when you are driving, or just seeking a pleasant diversion. Also, great if you have someone in the family that does not see as well as they used to. I sampled "The Importance of Being Ernest" and it was read by a cast, just as if it were being acted on stage. Good stuff.
