So What?

Why is this important?  You need to understand how the Library of Congress Classification (LCC) system works because that's how you find books in the library.  It is as simple as that.  The call number is the equivalent of a book's physical street address on the shelf, and without it you will be unable to locate a specific item.

An understanding of the LCC will allow you to browse books by topic and become familiar with the library's collection in your major area.  To find the books in your area, go to the library's online catalog at http://nsula.louislibraries.org/uhtbin/cgisirsi/0/0/0/38/X/POWER_SEARCH and search for your major as a subject.  This will show you where to find books, ebooks, government documents, and other material related to your field of study.
