What are call numbers? How do I search for a book by the call number?


A call number is a combination of letters and numbers assigned to an item (like a book or DVD) that categorize it by subject and determine its location in the library.  The UI Library uses the Library of Congress call number system. More information on how call numbers work can be found here: https://libguides.uidaho.edu/c.php?g=363237&p=2453519

You can find the call number of a book by searching in the library catalog.  Once you have the call number, this floor map of the library will help you locate the book itself.  We are happy to help if you have questions.
