Dewey Decimal System (Melvil Dewey)

The Dewey Decimal System, created by Melvil Dewey, is a method for organizing library books by subject using numerical codes. Each number reflects a specific topic, allowing books on similar subjects to be grouped together. The system divides knowledge into ten main classes, such as 000 for general works, 100 for philosophy, and 300 for social sciences, with further subdivisions for more specific topics. This structured approach makes it easier to locate and categorize books efficiently, streamlining library navigation and management.
