When was the last time you used a printed phone book? And the time before that?
Me, I can't even remember when it was. I look everything up online now. Even if you do use the printed books, though, you probably only need to keep the latest, and only one of it.
Go search around your house and purge all those old phone books to the recycling bin. They take up a bunch of space for very little value these days.

I’m very happy to report that few people in my building ever take that huuuuge two-parter Manhattan phone book. My then-boyfriend grabbed a set for me once thinking he was doing me a favor and I snuck both of ’em back downstairs the next day. Phone books are a waste of space and paper. I’m surprised they still make them.
