DEWEY DECIMAL SYSTEM DAY
Dewey Decimal System Day December 10th celebrates a system of classification and the man who invented it. On December 10, 1851, Melvil Dewey (1851-1931) was born. The librarian invented the Dewey Decimal system of library classification.
As the most widely used library classification system, the Dewey Decimal Classification (DDC) or Dewey Decimal System has been in use since 1876, the year when American Librarian Melvil Dewey developed and established it. Divided into ten main categories, the numerical system arranges mostly non-fiction publications.
Since its inception, modern libraries maintain the system using modern technologies. A schedule of expansions and revisions helps keep the system current and progressive, too. The DDC is the most widely used classification system in the world. Libraries in 135 countries around the world have translated the DDC into 30 different languages.
It is currently published by the Online Computer Library Center, Inc., and its editorial offices are located within the Decimal Classification Division of the Library of Congress.
Dewey’s interest in simplification led him to create a system that revolutionized library science. Born Melville Louis Kosuth Dewey in update New York, he was only 21 when he invented the Dewey Decimal Classification system.
He also established library standards and advanced library education. Dewey went on to help develop the American Library Association and founded and edited the Library Journal. As an entrepreneur, he sold library supplies. Dewey paved the way for new librarians by establishing the first library school at Columbia College in New York City and later became the director of the New York State Library in Albany.
