Overview

The Library of Congress Classification (LC) is a system of library classification that is used as a method to group like subjects together on library book shelves. Each book has a unique identification number that is found on the spine of books and in the library's catalog records. 

These unique shelf location numbers allow the books to be organized alphabetically by Library of Congress subject letters and numbers, grouping like subjects together for easier browsing.

Here's a sample call number, with an explanation for each line:

-   indicates the general subject area; presented on the shelf in alphabetical order

407 -  number line which indicates more specifically the subject area; presented on the shelf in numerical order within the B section

.A2713-  combination of letters and numbers that often represent the author's last name; presented on the shelf in alphabetical then decimal order

2001 - year of publication; presented chronologically on the shelf

Sometimes the library location is also indicated above the call number (for example REF for Reference, CURR, for the Curriculum Library, or DVD for our DVD collection).
