The Dewey Decimal Classification has been in use for over 148-years and continues to be one of the most popular book classification systems in the world-despite efforts to eliminate its use in some libraries. As of 2021, more than 200,000 libraries in over 134 different countries are estimated to still be using this system. Its popularity is directly related to the fact that this system does an amazing job of keeping books organized and also helps to make those books easier to find within a specific category. That’s why we should all take a few moments to celebrate Dewey Decimal System Day on December 10th and show it some love.
The History Of The Dewey Decimal System
Dewey Decimal System Day is observed annually on December 10th because that’s the day when Melvil Dewey was born. Melvil Dewey was an American librarian and library reformer who developed this library classification system in 1873 while he was employed at Amherst College Library. In 1876, he published “A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library.” He would use this pamphlet to encourage feedback from other librarians.
In 1885, the second edition of the Dewey Decimal System was published. Between this year and 1942, several different editions of this system were released with modifications and expansions of the system made as deemed necessary. By the late 1920s, this system was used in approximately 96% of responding public libraries and almost 90% of responding college libraries. In 1993, the first electronic version of this system was created. Over the past few years, however, the popularity of this system has begun to wane and some libraries have changed to alternative classification systems. It’s unknown if the use of this system will continue into the future or if it’s destined to become just another footnote.
