UDC, or Universal Decimal Classification, is a system for organizing and classifying library materials based on their subject matter. It divides the whole of knowledge into ten main classes, which are known as “divisions.” These divisions are:

Philosophy and psychology
Religion
Sociology
Language and literature
Natural sciences and mathematics
Technology (applied sciences)
Fine arts
Literature (belles-lettres)
History and geography
Recreation and social life

Each of these main classes is further divided into smaller categories or “subdivisions” based on the specific subject matter of the materials being classified. For example, the main class “Technology (applied sciences)” might be divided into subclasses such as “Agriculture,” “Engineering,” and “Medicine.” The subdivisions can then be further divided into more specific categories as needed.

Overall, UDC provides a comprehensive and systematic way of organizing library materials based on their subject matter, allowing library patrons to easily find and access the materials they need.

What does UDC stand for?

UDC stands for “Universal Decimal Classification.” It is a system for organizing and classifying library materials based on their subject matter. The UDC system was developed by Paul Otlet and Henri La Fontaine in the late 19th century, and it is still in use today in libraries around the world.

The UDC system is based on the idea of organizing materials according to their subject matter using a system of decimal numbers. Each number represents a different category or subclass, and the relationships between the categories are indicated by the placement of the numbers. For example, a book about the history of agriculture might be classified using the notation “63:631,” which would indicate that it is a book about the history of agriculture, which is a subclass of “Agriculture,” which is a subclass of “Technology (applied sciences).”

The UDC system is widely recognized as a comprehensive and flexible system for organizing and classifying library materials, and it continues to be widely used in libraries around the world.
