@Fa5t3r - The white pages directory is still used by a large number of demographics in a community. Not everyone has access to the internet and not every number is going to be available online either. And there are plenty of businesses where it makes much more sense for a copy of the white pages to be made available to employees who might need it, rather than giving them access to a computer or the internet.
I hope the white pages doesn't get shut down any time soon, because I just don't think we're ready for that as a society. Maybe one day the internet will be so widespread that no one will be without it, but until then lines of communication depend on access to old fashioned paper directories.
