Call Numbers Explained

Find a Book on the Shelf

To find a book on the Library shelves you will need to know its call number. Call numbers are printed on the spine of the book and are also listed in the Library Catalogue. They tell you where the book is located in the library.

The University of Canterbury library, like most academic libraries, uses the Library of Congress Classification system. In this system, the call numbers start with letters of the alphabet.

  • The first letter refers to the subject area, e.g. Q – Science
  • Sometimes another letter is added to refer to a more specific aspect of the subject, e.g. QD – Chemistry

Reading Call Numbers: Library of Congress Classification System

Read the call number line by line:

  • Read the first line in alphabetical order.
  • The first set of numbers that follow are read as whole numbers and are arranged numerically on the shelves.
