Universal Decimal Classification (UDC)

Universal Decimal Classification (UDC) is a system used to organize knowledge by categorizing subjects in a hierarchical manner. It assigns unique numbers to topics, allowing for easy identification and retrieval of information. For example, books about science, history, or art each fall under specific codes, enabling libraries and databases to efficiently arrange resources. UDC is particularly useful in libraries and information centers globally, as it supports multilingual and interdisciplinary access to knowledge, making it easier for users to find what they need across various subjects.
