CHICAGO, ILL.–January 9, 2007–Recognizing the significant changes that have taken place throughout the world, the 2007 edition of The World Book Encyclopedia includes thousands of new and revised articles across all disciplines, from science and technology and politics and religion, to society, the arts, and recreation.

Noted as “a first choice for libraries, schools and homes” by Booklist, among the new topics covered in the 22-volume World Book Encyclopedia are up-to-date coverage of the 2006 World Series and U.S. mid-term elections, a closer look at New Orleans and its progress in rebuilding, as well as Pluto’s new status as a dwarf planet. From Intelligent Design to Genocide, World Book also covers more sensitive topics with an unbiased, informative approach.

Hundreds of new biographies also are featured, including world leaders such as Canadian Prime Minister Stephen Harper and Liberian president Ellen Johnson-Sirleaf, the first elected president of an African country, and computer pioneers Michael Dell and Steve Jobs. Tennis great Roger Federer and basketball’s LeBron James as well as celebrities George Clooney and Johnny Depp also are among those joining the ranks of World Book biographies as are filmmakers Ken Burns and Gordon Parks and rapper Sean Combs (a.k.a. Diddy).

On a more scholarly level, the biography of Jesus Christ has been thoroughly revised to introduce the latest understanding and now includes illustrations of a number of religious art masterpieces.

The new edition also includes an expanded article on Time drawing on insights from physics and philosophy to help explain what we now know about one of the most enduring mysteries in human thought. A new article on Extremophile examines microscopic creatures living in harsh environments that are helping in development of new drugs, and an article on Anxiety Disorders explores one of the most common mental health disorders.

“The 2007 edition continues to focus on the characteristics that have made The World Book Encyclopedia an essential learning tool for 90 years, namely, its accuracy, authority, balance and comprehensibility,” said Paul Gazzolo, president of World Book. “Whether students are using our reference resources in print or online, they are assured the information is correct, developed by experts in the field with an unbiased approach, and written with the understanding of the student reader in mind.”
