Prospectus Supplement dated September 24, 1999 to
Prospectus dated August 13, 1999
This Supplement is part of, and should be read in conjunction with,
the Prospectus dated August 13, 1999 (the "Prospectus"). Defined terms used
herein (unless otherwise defined) have the meanings set forth in the Prospectus.
In the Prospectus, one of the selling stockholders is mistakenly
identified as "Ascent Partners, Inc." In all places where this name appears in
the Prospectus as a selling stockholder, it should be replaced with "Ted
Feierstein," the actual holder of the 2,542 shares of common stock of EarthWeb
that were identified in the Prospectus as owned by Ascent Partners, Inc.
