Final answer:
To find a book in the library, use the online catalog to find the call number and then locate the book on the appropriate floor or tier.
Step-by-step explanation:
When searching for a book in the library, it is important to know the call number and the floor or tier where the book is located.
To find the call number, you can use the library's online catalog, such as Quick Search, to look up the book. The call number is a unique code assigned to each book that helps organize the library's collection, using systems like the Dewey Decimal system or the Library of Congress system.
Once you have the call number, you can check the library's floor or tier maps to locate the specific area where the book is shelved. Each library may have a different layout, so it's important to familiarize yourself with the library's organization system.
