Is there a whitepage web site that allows you to view information as a
phone book would -- e.g. scan all alpha listings by last name or
business name -- rather than requiring that you enter information,
then search

It would make for one extremely large web page, too large to be of
practical use. And if it weren't all on one huge page, there would
need to be some other way of telling the site which section you wished
to look at.

If you mean a service which is broken up into, say, listings
containing the same first three characters... ske, ski, sko, sku, sla
etc... I haven't seen one online.
