View source for Comparison of Dewey and Library of Congress subject classification

{{Short description|None}}
This is a conversion chart showing how the [[Dewey Decimal Classification|Dewey Decimal]] and [[Library of Congress Classification]] systems organize resources by concept, in part for the purpose of assigning [[Wiktionary:call number|call numbers]].  These two systems account for over 95% of the classification in [[United States]] libraries, and are used widely around the world.

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
* [[Library of Congress Classification]]—high level categories
