UDC

UDC, or Universal Decimal Classification, is a system used by libraries and organizations to organize and categorize information and documents. It assigns a unique numeric code to each subject or topic, making it easier to locate and group related materials efficiently. Think of it as a detailed filing system that covers almost every area of knowledge, helping users find books, articles, or resources quickly based on their subject. It’s widely used internationally to maintain consistency and order in managing large collections of information.
