This week, This American Life aired an episode that tells "stories of people who believe a book changed their life." (Click here, scroll down the page a little, and then click on "Full Episode.") It's a good program for book lovers, but don't expect to hear about Shakespeare, Dostoevsky, or Salinger. This American Life doesn't quite do things that way. They have their own unique take on things. But if you want a more traditional list of life-altering books, then check out this collection created by our readers and feel free to add your own books to the comments. The more, the merrier.
