Comparison of Dewey and Library of Congress subject classification
From Wikipedia, the free encyclopedia
This is a comparison chart showing how the Dewey Decimal system and the Library of Congress organize materials by subject for the purpose of assigning call numbers. These two systems account for over 95% of the call number classification in libraries in the United States, and are widely used in many other countries.
The chart includes all ninety-nine second level (two-digit) DDC classes (040 is not assigned), and should include all second level (two-digit) LCC classes. Where a class in one system maps to several classes in other system, it will be listed multiple times (e.g. DDC class 551).
Additional information on these classification plans are available at:
- Dewey Decimal Classification -- high level categories, with recursive links to lower level categories
- Library of Congress Classification -- high level categories
