DEWEY DECIMAL SYSTEM DAY – December 10

The Dewey Decimal Classification (DDC) or Dewey Decimal System, the year when American Librarian Melvil Dewey invented and established it, has been in use since 1876, the year when American Librarian Melvil Dewey invented and established it. The numerical system organizes mainly non-fiction books, dividing them into ten main categories.

Modern libraries maintain the system using modern technologies since its inception. Also, a series of expansions and revisions helps keep the system current and progressive. The DDC is the world's most widely used classification system. The DDC has been translated into 30 different languages by libraries in 135 countries around the world.

It is currently published by the Online Computer Library Center, Inc., and its editorial offices are located within the Library of Congress' Decimal Classification Division.
