RE:      VANGUARD WORLD FUNDS
         FILE NO. 2-1726


Dear Mr. Sandoe,

         The following responds to your comments of April 14, 2008 on the
post-effective amendment of the registration statement of the above-referenced
registrant. You commented on Post-Effective Amendment No. 109 that was filed on
February 26, 2008.

     COMMENT:  On page 10 of the  International  Growth Fund prospectus,  please
clarify what you mean by "scarce assets."

     RESPONSE:  We have added  appropriate  language  to clarify  the meaning of
"scarce  assets," as follows:  "Scarce assets can include  traditional  tangible
assets (such as land or property),  intangible assets (such as a strong brand or
reputation), and organizational assets (such as a unique corporate culture)."

     COMMENT:  Page 17 of the  International  Growth Fund prospectus states that
Ms.  Maisonneuve and Mr. Dobbs have "jointly managed" the Schroder's  portion of
the Fund since  2005.  If these two  individuals  have equal  authority,  please
consider using the phrase "co-manage," as Vanguard does in other prospectuses.

Response:  We will make the suggested change.

               *        *        *       *        *        *        *        *

As required by the SEC, the Funds acknowledge that:

                o The Fund is responsible for the adequacy and accuracy of the
                  disclosure in the filing.
                o Staff comments or changes in response to staff comments in the
                  filings reviewed by the staff do not foreclose the Commission
                  from taking any action with respect to the filing.
                o The Fund may not assert staff comments as a defense in any
                  proceeding initiated by the Commission or any person under the
                  federal securities laws of the United States.
