Understanding the Library of Congress Classification System
 
Most of the books in our library are classified using the Library of Congress system. Because this system arranges materials by subject, you can browse books by the call number that matches your topic area (i.e. Q = Science, N = Art, and F = History). This is a quick way to find books on a general subject and is often a good way to discover sources you wouldn't have thought to look for.

Bibliography
The library uses the system to classify:
the majority of books, videos, DVDs, and CDs.
The system arranges books by:
letters signifying subjects, see table

To read an LC call number, look at it line by line, starting at the top:

LC Example Number: QC 467. M456 1999
This would be a book on the Physics of Light, probably written by someone with the last name beginning with the letter M, and published in 1999. The numbers represent more specific subject breakdowns, within the lettered categories. For example: E 456 through E 655 is the call number range for works on the US Civil War; HQ 12 through HQ 449 represents materials on the topic of Sexual Life; and PZ 3 through PZ 4 includes Modern Fiction.
This might seem confusing. If it is, consult a helpful Librarian for assistance.

To find items with LC call numbers in the Courtright Memorial Library, use the following chart:

 

A through K are located on the 2nd floor;
L and N through Z are located on the 3rd floor;
M are located on the lower level (in the Music Collection).
Anything with the designation Folio (too large for normal shelves) is located on the 3rd floor
