Understanding call numbers

What is a call number?

A call number classifies an item by subject. They are used so resources on the same topic are grouped together on the shelf, which makes it easier to browse materials in the same subject area. A call number shows you the exact position of the item within the Library, the collection, and the subject area.

The majority of items held in the ANU Library collection are classified according to a scheme called the Library of Congress (LC) classification scheme. Other schemes used by the ANU Library include the Moys, Bliss, Dewey Decimal and Harvard Yenching systems.
