Understanding the Dewey Decimal System Chart
The Dewey Decimal System Chart provides a clear and organized way to understand all areas of knowledge. It does this by dividing information into different categories, much like how a library organizes its books.
The Ten Main Classes of Knowledge
At the heart of this system are ten main classes that encompass all subjects:
- 000-099: Computer Science, Information & General Works
- 100-199: Philosophy & Psychology
- 200-299: Religion
- 300-399: Social Sciences
- 400-499: Language
- 500-599: Science
- 600-699: Technology
- 700-799: Arts & Recreation
- 800-899: Literature
- 900-999: History & Geography
Each main class is further divided into ten divisions, and each division has ten sections. This structure, based on decimals, allows for precise categorization of materials.
For example, under the 500s (Science):
500: General Science
510: Mathematics
520: Astronomy
530: Physics
How the Chart Works
The chart uses colors and indentation to make it easy to navigate. Related subjects are grouped together, creating connections between topics. For instance, if a student is studying physics, they can easily find resources on mathematics by following the visual hierarchy.
The decimal notation system also allows for detailed classification of specific topics. For example, a book about quantum mechanics might be classified as 530.12, where:
- 500 = Science
- 530 = Physics
- .12 = Quantum Theory
This organized system helps students see how different subjects are related and find more specific information within broader areas of knowledge. The visual chart is a helpful tool for understanding these connections and finding resources in the library efficiently.
