What does DDC stands for?

DDC stands for Dewey Decimal Classification. It is a widely used library classification system that was developed by Melvil Dewey in the late 19th century. The DDC is based on a hierarchical structure, with 10 main classes at the top and more specific categories and subcategories below them. Each class, category, and subcategory is assigned a unique decimal number, which is used to identify and locate materials within the classification system.

The DDC is used in libraries around the world to organize and classify books and other materials according to subject matter. It is particularly popular in public libraries and school libraries, as it is relatively easy to use and understand. The DDC is regularly updated and revised to reflect changes in knowledge and subject matter, and it is considered to be an essential tool for organizing and accessing information in libraries.

Dewey Decimal Classification (DDC) system

The Dewey Decimal Classification (DDC) system is a system of library classification used to organize and arrange books and other materials in a library. It was developed by Melvil Dewey in the 1870s and is still in widespread use today.

The DDC is based on a system of ten main classes, each representing a broad subject area. These main classes are further divided into smaller divisions, and then into even smaller sections until each book or material is assigned a unique classification number. The classification numbers are arranged in a decimal format, with the first digit representing the main class, the second and third digits representing the division, and so on.

For example, the number “500” represents the natural sciences and mathematics, while the number “540” represents chemistry and “550” represents earth sciences. Within the earth sciences section, the number “550.1” represents geology, and “550.2” represents meteorology.

The DDC is used to organize and arrange books and materials in a library, and to help library patrons find the materials they are looking for. It is also used to create library catalogs and bibliographies.
