Q. What is a call number?


Every book at the library has it's own call number, which tells us where the book is located in the library, like a little address. In OneSearch, the book's information tells you which level the book is located on, but that only directs you so far! The call number can be used to help you navigate through the shelves.

Let's use this call number as an example: 686.22 A384. This book is located on Level 5, and is called Aspects of Contemporary Book Design.

Take a look at the first three numbers in the call number, these will help you narrow down which shelf on Level 5 the book is sitting on. Look at the signs on the ends of the shelves that show which range of numbers are on that shelf. Once you find a shelf with a sign that says (for example) "680-688", you've found the right one! Look at the numbers on the spines of the books on the shelf until you get to some with the number 686 at the beginning. Look even more closely until you find 686.22, and even more closely to find the 686.22 As. Those would be at the beginning of the 686.22s, and I'm sure that you would spot the book title at this point!
