Book Location Guide

What is a Call Number?

Each library book is given a call number according to the subject matter of the work under the Library of Congress Classification System. A call number is usually placed on the spine label of a library book, and listed in the library's online catalog, indicating the book's location in the library. Once you find the call number of the book that you are looking for, you may use the following location guide or stack maps to find the book. If you need help, please contact the Circulation Desk on the First Floor of the Library.
