Last week, a group of volunteers, the Dummies Man and Dewey the Dinosaur, the mascot of the Gwinnett County Public Library in Georgia, unloaded one copy of every Dummies book in print--more than 1,800 titles--at the library's headquarters. The library won a contest, part of the 20th anniversary celebration of the Dummies series, that challenged libraries to create a Dummies fan page on Facebook and garner the most "likes" by May 1. Gwinnett County Public Library's page was liked by 5,002 people. Runners-up were the Salem-South Lyon District Library in South Lyon, Mich., and the Bloomfield Public Library in Bloomfield, N.J.
