The books on our shelves are arranged using the Library of Congress Classification system. Each book in the library has a unique “call number”, which is a combination of letters and numbers that are used to place books in alphabetical and numerical order. When you find a book in our online catalog, you can use the call number to find the book. The call number is placed on the lower part of the spine of the book.
In our catalog, the call numbers are displayed as a single line, but the spine label displays the call number as 3 to 5 lines. The call number is always read from left to right, then from top to bottom (when applicable).
