Dewey Decimal Classification

Dewey Decimal Classification تصنيف ديوى العشرى

The Dewey decimal system coordinates materials on the same subject and on related subjects to make items easier to find on the shelves by using a combination of letters and numbers.

The Dewey system has ten main classes, which are listed below.

000 Generalities
100 Philosophy and Psychology
200 Religion
300 Social Science
400 Language
500 Natural Science and Mathematics
600 Technology (Applied Sciences)
700 Arts
800 Literature
900 Geography and History

Each of the above classes each has ten divisions. These divisions are further divided-and then further divided. Each division becomes more specific. The more numbers, the more specific the subject. In this way, the Dewey classification system progresses from the general to the specific. For a detailed summary for each number see the DeweyThe decimal place is used to make the number even more specific.
