Universal Decimal Classification

Universal Decimal Classification (UDC) is a system used to organize and classify books and other materials in libraries. It breaks down knowledge into categories, each represented by a unique number, covering subjects like science, art, and technology. For example, a book about agriculture might be assigned a specific UDC number that helps librarians and users find it easily. This system allows for efficient retrieval of information and ensures that similar topics are grouped together, making it easier to locate resources on a particular subject. UDC is widely used in libraries around the world.
