Library of Congress Classification System

The classification system developed and used at the Library of Congress, beginning in 1897. It typifies the enumerative method of classification and allows for continued growth and expansion. The notation or numbering scheme is mixed using a combination of letters and numbers. The basic outline is as follows: 

A General works
B Philosophy, psychology, religion
C Auxiliary science of history
D Universal and Old World history  except America
E-F America
G Geography, anthropology, folklore, customs, sports
H Social sciences, economics
J Political science
L Education
M Music
N Fine arts
P Language and literature
Q Science
R Medicine
S Agriculture, hunting
T Technology
U Military science
V Naval science
Z Bibliography and library Science.

The Virginia Tech Libraries uses the Library of Congress Classification System for the majority of our collections.
