Library of Congress call numbers

A call number is similar to a street address, it helps you to find an item in a specific spot on the shelf, on a specific floor in our library. Each item has a unique call number based on the subject, but items on the same subject have similar call numbers. This means that related items are shelved together, making it easy for you to discover them by browsing the shelves.

The call number is usually located on (or near) the lower spine of the item.

Read call numbers from left to right, Example: D810.S7M577 2004

On the shelf, read call numbers from top to bottom
