Step-by-Step Guide to Learning the Dewey Decimal System
Step 1: Understand the Basic Structure
The Dewey Decimal System divides knowledge into 10 main categories (000–900), each represented by a three-digit number. For example:
- 000–099: General works, computer science, and information.
- 100–199: Philosophy and psychology.
- 200–299: Religion.
- 300–399: Social sciences.
Each category is further divided into subdivisions using decimals. As an example, 500–599 covers natural sciences, with 510–519 focusing on mathematics.
Step 2: Learn Decimal Notation and Extensions
The Dewey system uses decimals to add specificity. For example:
- 512.Think about it: 8 = Algebraic equations. - 512.81 = Polynomial equations.
Additional numbers (e.This leads to g. , 09, 10, 20) denote geographical or historical context.
