When you find a book in Library Search that’s listed as “Available” with a green check mark next to it. That means it’s physically on the shelf in the library and ready to be checked out.

To locate it, you’ll use something called a call number, which is a unique code assigned to each item. These call numbers follow the Library of Congress Classification System, which groups books by subject. Understanding how to read a call number will help you find exactly where a book is located—and may even lead you to other useful titles nearby on the same topic.

Check out the example below which is also linked to the live search result or go to Library Search to find a source you're interested in and check out it's availability and call number.
