World Book Launches World Book Mobile Content Licensing Initiative

World Book, Inc. (http://www.worldbook.com)
today announced the launch of World Book Mobile, a broad-based
licensing program significantly extending the volume of licensed
content it is making available to mobile application developers and
distributors.

"World Book has a tremendous amount of content. World Book Mobile is a
logical extension of our digital content strategy enabling us to work
with leading mobile application providers to deliver accurate,
authoritative information wherever and whenever consumers want access,"
said World Book President Paul Gazzolo.

World Book Mobile will have access to content from more than 90 World
Book titles as well as a vast selection of customizable datasets, which
can be adapted and integrated into a variety of digital applications,
including web-based products, cellular products, and digital games.
Among the topic-specific datasets are: history, geography, children's
science, science history, general science, literature, art, music,
biography, and general reference. Also available is an image dataset
including more than 20,000 illustrations, diagrams, graphs, and maps,
with a particular emphasis on science, history, nature, and animals.

Among the first developers to leverage World Book's broad array of digital contents is Mobifusion, Inc. (http://www.mobifusion),
a global developer and publisher of mobile applications and
technologies, which has developed two titles to be published under the
World Book Mobile Imprint Baby's First Book and World of Animals, a
part of the award-winning Childcraft series. Electronic editions of
these resources will be delivered on mobile devices leveraging
Mobifusion's unique patented m-publishing technologies designed to
provide rich information and entertainment products across wireless
platforms.

"With the World Book children's content, we're able to deliver
innovative applications for busy parents on the go, allowing them easy
access to content that will delight children," said Pavan Mandhani,
founder and CEO of Mobifusion.
