How to Locate a Book on the Shelf
To find an item in the library you need to know its call number. Each item in the ORU Library has its own unique call number that is 1) on a label that is usually taped on the spine of the book or other item and 2) listed in the library catalog record.
After you find an item in the library catalog, record the call number, go to the location in the library, and locate the item on the shelf.
For example, if you use the opens new windowLibrary Catalog and key in Revell Dictionary, results include the call number, location, status, and item details.
How to Read a Call Number
Call numbers are read one row at a time. Each row of the call number helps identify the book or item.
