Do Casperites Still Use Telephone Books?

Directory, telephone book, yellow pages, white pages... they have so many different names. Whatever you call it, do you actually still use one?

My apartment complex has been littered with a good half a dozen for about the last week and not one person in my building seems to care. Although I do have them in my place, it's only temporarily, which means only until I take them to the recycling bins.
