Dewey Decimal System (not related)

The Dewey Decimal System is a method used by libraries to organize and categorize books systematically. It assigns each book a unique number based on its subject matter, covering 10 main categories, such as sciences, history, and arts. These main categories are further divided into more specific topics using decimal points, allowing precise classification. This system helps users easily locate books on particular subjects, as items are arranged numerically on shelves. Overall, it streamlines finding and managing library resources, making it more efficient for both staff and patrons.
