At ECPI University Libraries, print books are arranged using the Dewey Decimal System.
A Dewey Decimal call number acts like a book’s “address” on the library shelf. Call numbers are displayed in the Library Catalog and can be found on the spine of each library book. A standard Dewey Decimal call number will look like this:
The Dewey Decimal system is divided into ten major sections.
- 000 – Computer science, information and general works
- 100 – Philosophy, ethics, and psychology
- 200 – Religion
- 300 – Social sciences (e.g. economics, education, criminal justice, law, and politics)
- 400 – Language
- 500 – Science and mathematics
- 600 – Applied science and technology (e.g. engineering, business management, nursing, and medicine)
- 700 – Arts and recreation
- 800 – Literature
- 900 – History and geography
