The World Book Encyclopedia
The World Book Encyclopedia is the first choice for students, librarians, and teachers.
The Spinescape® design for the 2012 edition--Swifter, Higher, Stronger--salutes the athletic activities that help keep people healthy and fit. Men and women take part in sports for personal enjoyment, for love of competition, and for physical conditioning. Played individually or in teams, sports help develop the speed, strength, and flexibility that people need to remain active throughout their lives. Just as athletes strive to do their personal best, the editors and staff of The World Book Encyclopedia work to help readers achieve their personal best in learning. http://www.worldbook.com
