Dewey Decimal System

The Dewey Decimal System is a method used by libraries to organize books by subject. It divides knowledge into ten main categories, each represented by a three-digit number ranging from 000 to 999. For example, books about computers are found in the 000s, while history is in the 900s. Within each category, subjects are further divided into subcategories with specific numbers. This system helps users easily locate books and materials, making it efficient to find information on a wide range of topics. It’s a straightforward way to categorize and access the vast amount of knowledge available in libraries.
