9.1) Library of Congress Classification System (L.C) vs Dewey Decimal Classification System (D.D.C)

Library of Congress Classification (LC)

In library science, a method of classifying knowledge for the purpose of cataloging books and other library materials, devised by the staff of the Library of Congress in Washington, D.C.
In the Library of Congress Classification system (familiarly known as LC), all knowledge is divided into 21 large classes, indicated more or less arbitrarily by capital letters—as

follows:
A General Works
B Philosophy, Psychology, and Religion
C Auxiliary Sciences of History
D General and Old World History
E History of America
F History of the United States and British, Dutch, French, and Latin America
G Geography, Anthropology, and Recreation
H Social Sciences
J Political Science
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, and General Information Resources

Within each of these classes, material is arranged from general considerations to specific treatments and from theory to practical applications; specific topics are indicated by combinations of capital letters, and further subject breakdowns by 3-digit numbers. The classification scheme is continually revised.

Dewey Decimal Classification (DDC)

Dewey Decimal Classification (familiarly known as DDC), in library science, a method of classifying knowledge for the purpose of cataloging books and other library materials, devised by Melvil Dewey.
The system is made up of ten main classes or categories, each divided into ten secondary classes or subcategories, each having ten subdivisions.
• 000 – Computer science, information & general works
