Library of Congress Call Numbers

While you might be more familiar with the Dewey Decimal System for classifying library materials, the Armacost Library (and most other academic libraries) uses the Library of Congress Call Numbers to organize materials. Library of Congress Call Numbers arrange materials by subject. Here is a list of the general subjects, though each can be divided into more specific subjects.

A: General Works
B: Philosophy, Psychology, Religion
C: Auxiliary Sciences of History
D: History: Europe, Asia, Africa
E-F: History: America
G: Geography, Anthropology, Recreation
H: Social Sciences
K: Law
L: Education
M: Music
N: Fine Arts
P: Language and Literature
Q: Science
R: Medicine
S: Agriculture
T: Technology
U: Military Science
V: Naval Science
Z: Bibliography, Library Science, Information Resources

Reading a Call Number

Each call number has three parts: the class number, the Cutter number, and the date. Together, they help the library organize items and help you find them. 

class number One or more capital letters at the beginning of a call number representing the broad subject area plus number from 1-9999 representing specific subdivisions of topics. The class number will be the same for items of the same subject class.
Cutter number This number begins with a period followed by a capital letter (typically the author's last name) and a number. The Cutter number helps alphabetize works within a particular subject. 
date The date that the work was published. Dates are typically added to ensure that each call number remains unique for each book.

For example, the book Poetics of Cinema by David Bordwell has the call number PN1994 .B5735 2008 to indicate that it is a book about motion pictures written by David Bordwell and published in 2008. 

When using the library catalog to find an item's call number, note that the location of the item may vary, even if it has a similar call number to another item. For example, Poetics of Cinema is located in the general collection. 

While the Schirmer Encyclopedia of Film, which has the call number PN1993.45 .G65 2007, is located in the Reference Collection.
