What Is the Dewey Decimal Classification (DDC) System?
The Dewey Decimal Classification (DDC) system is a way to organize books and knowledge. It divides all subjects into 10 main categories and then into smaller subcategories. This helps group books on the same topic together, making it easier for library users to find them.
The 10 Main Categories of DDC:
000 – General Knowledge
100 – Philosophy and Psychology
200 – Religion
300 – Social Sciences
400 – Language
500 – Science and Mathematics
600 – Technology and Applied Sciences
700 – Arts and Recreation
800 – Literature
900 – History and Geography

How the DDC System Works
The DDC system organizes resources by discipline, providing a clear and logical path from broad categories to specific topics. Each item in a library is assigned a call number, which acts as its “address” on the shelf. This ensures that related materials are grouped together, making it easier for library users to browse and locate resources.
For example, under the 300 – Social Sciences category, you’ll find subcategories like:
300 Social sciences
310 Statistics
320 Political science
330 Economics
340 Law
350 Public administration & military science
360 Social problems & social services
370 Education
380 Commerce, communications & transportation
390 Customs, etiquette & folklore
This makes it easy to find books about the same topic without searching all over the library.
