Phone books: Do you use them?

My annual delivery of phone books today made me realize that I can't remember the last time I actually used one of them. Every year I get a thick residential listing and a second equally thick book for businesses, plus another book or two from rival companies who try to get me to think their listings are better somehow. All this paper wasted, and who actually uses phone books anymore? If I'm at home or work, I look up a number online; I know some people who don't care about the charge and just call information. The one place I might actually use a phone book, a public telephone, generally doesn't have them anymore.

Does anyone still use a phone book? How long before they go the way of the dinosaur?

Jam it back in, in the dark.
