The Dewey Decimal System is named after its creator, Melvil Dewey, an American librarian who developed this library classification system in 1876. It organizes library materials by dividing them into ten main classes, each further subdivided, making it easier for users to locate and access books.
What is the Dewey Decimal System?
The Dewey Decimal System is a library classification method that categorizes books into ten primary classes, ranging from 000 to 999. Each class covers a broad subject area, which is then divided into more specific topics. This system helps libraries maintain an organized collection and enables patrons to find books efficiently.
How Does the Dewey Decimal System Work?
The system assigns a three-digit number to each book based on its subject matter. These numbers are known as "Dewey Decimal numbers" or "call numbers." Each main class is divided into ten divisions, and each division into ten sections, allowing for detailed categorization. For example:
- 000 – 099: General works, Computer science, Information
- 100 – 199: Philosophy and Psychology
- 200 – 299: Religion
- 300 – 399: Social sciences
- 400 – 499: Language
- 500 – 599: Science
- 600 – 699: Technology
- 700 – 799: Arts and Recreation
- 800 – 899: Literature
- 900 – 999: History and Geography
