Today is Melville Louis Kossuth (Melvil) Dewey's birthday. He was born December 10, 1851. Dewey is best remembered for inventing the Dewey Decimal System , which is a book organization system. The Belk Library's Instructional Material's Center, which mirrors a K-12 school libary, uses this system. The library's main stacks use the Library of Congress Classifcation System . He also helped found the American Library Association, and was interested in simplfying spelling.
