DeLorme had a program a few years ago called Phone Search USA which integrated into Street Atlas. You could search on a name or number and then get directions to the address. There were 3 CDs that covered the entire US - white and yellow pages. It was pretty slick but I haven't seen any updates recently. I still use it occasionally when I need to look up a number/address, but I think these kinds of programs became unnecessary once you could do the same thing on the internet.
