Dewey Decimal System Day- December 10th
Dewey Decimal System Day, celebrated annually on December 10th, marks the birth of Melvil Dewey, the inventor of one of the most widely used classification systems for organizing library materials. On Deember 10th every year, we honor Dewey’s profound impact on the world of libraries and education, as his Dewey Decimal Classification (DDC) system continues to shape how we access knowledge in libraries worldwide.
The Birth of the Dewey Decimal System
In 1876, at just 25 years old, Melvil Dewey introduced his revolutionary library classification system, which would go on to become a cornerstone of modern library organization. Before Dewey’s system, libraries had no standardized way of cataloging their vast collections. Dewey sought to simplify the process and create a universal method that could be used across libraries to categorize and organize books and other materials, making it easier for librarians and readers to find the resources they needed.
The Dewey Decimal Classification system divides all knowledge into ten main classes, each represented by a number ranging from 000 to 999. Each class is further divided into divisions and sections, which are represented by additional numbers, creating a hierarchical structure that allows for a detailed categorization of subjects. This decimal-based system was designed to be flexible and adaptable, able to accommodate new subjects as they arose.
How the Dewey Decimal System Works
The Dewey Decimal Classification system assigns a unique number to each book or library material based on its subject matter. The ten main classes are:
- 000 – General Works
Covers books on reference materials, encyclopedias, and bibliographies. - 100 – Philosophy and Psychology
Includes works on philosophy, logic, ethics, and psychology. - 200 – Religion
This class encompasses books on world religions, theology, and mythology. - 300 – Social Sciences
Covers subjects like sociology, economics, law, education, and political science. - 400 – Language
Includes works on linguistics, grammar, dictionaries, and language learning. - 500 – Natural Sciences and Mathematics
Encompasses books on biology, chemistry, physics, astronomy, and mathematics. - 600 – Technology and Applied Sciences
Focuses on engineering, medicine, agriculture, and various applied sciences. - 700 – Arts and Recreation
Includes books on visual arts, music, sports, and leisure activities. - 800 – Literature
Covers world literature, poetry, drama, and literary criticism. - 900 – History and Geography
Encompasses works on historical events, geography, and travel.
Each subject area is subdivided, creating more specific categories for easy navigation. For example, a book on astronomy might fall under 523 – Astronomy in the 500 class, while a book on European history could be found in 940 – General history of Europe under the 900 class.
This system allows libraries to maintain an organized structure, where each book is easily placed in its designated spot and located quickly by library patrons.
The Evolution and Impact of the Dewey Decimal System
When Dewey first proposed his system, libraries were organized in a variety of ways, making it difficult for users to find books across different locations. By standardizing the classification of knowledge, Dewey’s system revolutionized libraries, making information more accessible and user-friendly. Over time, the Dewey Decimal System has been refined and updated to reflect new developments in science, technology, and culture.
Today, the DDC is used by over 200,000 libraries in more than 135 countries, and it remains one of the most recognized and widely employed library classification systems in the world. Its impact extends beyond traditional libraries, as digital libraries and archives have also adopted the system for organizing online materials.

- Online Celebrations: In today’s digital age, many libraries and educators take to social media or virtual platforms to share information about Dewey and the Dewey Decimal System, encouraging people to appreciate the simplicity and accessibility it has brought to information organization.
The Legacy of Melvil Dewey
Melvil Dewey’s contributions to library science go far beyond the Dewey Decimal System. He was a key figure in the establishment of the American Library Association (ALA) and played a pivotal role in promoting library education and standards. Dewey was also an advocate for universal access to education, and his work helped lay the foundation for the modern library system that serves people of all ages and backgrounds.
