Comparison of Dewey and Library of Congress subject classification

This is a comparison chart showing how the Dewey Decimal and Library of Congress Classification systems organize resources by concept, in part for the purpose of assigning call numbers. These two systems account for over 95% of the classification in United States libraries, and are used widely worldwide.

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 is available at:

• Dewey Decimal Classification -- high level categories, with links to lower level categories : The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876.                                                                                   EX ,The classes are:
  • 000 – Computer science, information and general works
  • 100 – Philosophy and psychology
  • 200 – Religion
  • 300 – Social sciences
  • 400 – Language
  It has been greatly modified and expanded through 23 major revisions, the most recent in 2011. This system organizes books on library shelves in a specific and repeatable order that makes it easy to find any book and return it to its proper place. The system is used in 200,000 libraries in at least 135 countries.
  
  

Library of Congress Classification -- high level categories :The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries, for example, Australi and Taiwan, R.O.C. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC).
