Library cataloging and classification
main topic

The Dewey Decimal Classification (DDC), also known as the Dewey Decimal System, is a proprietary library classification system first published by Melvil Dewey in 1876. It has been revised and expanded through 23 major editions, the latest issued in 2011. The system is used in libraries around the world to organize books and other materials by subject.

History

The Dewey Decimal Classification was created by Melvil Dewey in 1873 and first published in 1876. Dewey was a librarian and educator who sought to create a system that would make it easier to find books in a library. The system was initially based on the idea of dividing all knowledge into ten main classes, each of which was further divided into ten divisions, and each division into ten sections.

Structure

The DDC is structured around ten main classes, each identified by a three-digit number. These classes are:

• 000 – Computer science, Information, and General works
• 100 – Philosophy and Psychology
• 200 – Religion
• 300 – Social sciences
• 400 – Language
• 500 – Science
• 600 – Technology
• 700 – Arts and Recreation
• 800 – Literature
• 900 – History and Geography

Each main class is further divided into ten divisions, and each division into ten sections, allowing for a highly detailed classification system.

Usage

The Dewey Decimal Classification is used in libraries around the world, particularly in public and school libraries. It allows for the systematic arrangement of books and other materials, making it easier for users to find what they are looking for. The system is also used in some academic libraries, although many academic libraries use the Library of Congress Classification system instead.

Editions

The DDC has been revised and expanded through 23 major editions. The latest edition, published in 2011, includes updates and revisions to reflect changes in knowledge and technology. The system is maintained by the OCLC (Online Computer Library Center), which also provides online access to the classification schedules.

Criticism

The Dewey Decimal Classification has been criticized for its Western-centric and Eurocentric biases, particularly in the classification of religion and history. Critics argue that the system reflects the cultural and intellectual biases of its time and does not adequately represent non-Western perspectives.
