What has 18 wheels, expands to three times its road width, contains priceless historical treasures, and rolls into Eau Claire on Nov. 19 and 20? It’s the Library of Congress’ newest traveling exhibit, the Gateway to Knowledge. For the next three weeks the exhibit will be in Eau Claire, Fond du Lac, and Janesville. The Gateway to Knowledge is an exhibit spearheaded by Abby and Emily Rapoport, who wanted it to travel around the nation. It focuses on the history of the library, and the creators hope to bring it to the people, offering specialized programs for teachers plus computerized terminals. Doors will be open from 10am to 6pm and it will be displayed in the parking lot of Oakwood Mall. For more information visit the Library of Congress website, www.loc.gov.
