The library catalogue provides information about all of the resources held in the Australian Catholic University Library collections.

It provides details about various aspects of materials held, including - author, title, format of material, subject content and physical location.

The physical location is represented by a call number, based on the Dewey Decimal classification scheme. This number provides the location of an item on the library shelves. Items are shelved in numerical order.
