      Wiley Completes Acquisition of Blackwell Publishing (Holdings) Ltd.

Hoboken, N.J., and Oxford, U.K., February 5, 2007-- John Wiley & Sons, Inc.
(NYSE:JWa) (NYSE:JWb) announced today that it has finalized the acquisition of
the outstanding shares of Blackwell Publishing (Holdings) Ltd., one of the
world's foremost academic and professional publishers. The purchase price of
(pound)572 million was financed with a combination of debt and cash.

Blackwell's publishing program is being merged with Wiley's global scientific,
technical, and medical business. The merged business is now the largest of the
three businesses of John Wiley & Sons, Inc.; its other businesses are
Professional/Trade and Higher Education.

"Wiley begins our third century of publishing by embarking on the path of
growth and expansion, with our new colleagues," said William J. Pesce, Wiley's
President and Chief Executive Officer. "It is an extraordinary milestone in
our Company's remarkable history."

The integration of the businesses is being guided by a best practices
approach. Leadership roles are being assumed by colleagues from both
companies. Mr. Pesce announced the appointment of Wiley's Senior Vice
President, STM Publishing Eric A. Swanson to lead the merged business and
Blackwell CEO Rene Olivieri to serve as its Chief Operating Officer. Mr.
Olivieri is co-leader of the transition team along with Wiley Europe's Chief
Operating Officer, Stephen Smith.

Responsibility to stakeholders is an important part of the vision guiding the
merger. "We want to set the standard for publishing for the scientists,
physicians, professionals and scholars who are our authors and readers,"
continued Mr. Pesce, "For our authors and society partners, we intend to
provide best of class service through our extensive network of editorial,
production, marketing, and sales talent. For our customers, we intend to
provide more access to more content to more people than ever before in the
history of the two companies. For our colleagues, we intend to provide
intellectually stimulating and rewarding opportunities."

The combined business and the constituencies it serves will benefit from its
collaborative, customer- and partner-friendly approach. Moreover, the combined
companies will be able to invest more in online capabilities than either could
as separate entities. Global market reach will be strengthened and extended.
Wiley and Blackwell are two of the world's most respected global publishers.
Together, the two companies will publish approximately 1,250 scholarly
peer-reviewed journals (over 1 million pages) and an extensive collection of
books with global appeal.
