Understanding Dewey

 

So what's the deal with Dewey?

The Dewey Decimal Classification (DDC) system is a general knowledge organization tool used in libraries and other institution across the world. 

In the DDC, basic classes are organized by disciplines or fields of study. At the broadest level, the DDC is divided into ten main classes, which together cover the entire world of knowledge. Each main class is further divided into ten divisions, and each division into ten sections (not all the numbers for the divisions and sections have been used).

  • The first digit in each three-digit number represents the main class. For example, 600 represents technology.
  • The second digit in each three-digit number indicates the division. For example, 600 is used for general works on technology, 610 for medicine and health, 620 for engineering, 630 for agriculture.
  • The third digit in each three digit number indicates the section. Thus, 610 is used for general works on medicine and health, 611 for human anatomy, 612 for human physiology, 613 for personal health and safety.
