InfoSpace is a new Web based phone directory that claims to be the "most comprehensive on the Internet," with over 112 million listings. Users can search people, businesses, yellow pages, and fax directories in the U.S. and Canada. A blue pages government and toll free 800 number directory is available for the U.S. only at this time. Forthcoming services include a large email search service and map-based individual, business, and government directories. As always, there is no guarantee that information found is correct (as it is based on telephone directory listings), but the sheer magnitude of this venture, along with the fact that it includes Canadian as well as American listings, merits a look at InfoSpace.
