A post today on 025.431: The Dewey Blog from the DDC team at OCLC (publishers of the classification) included a chart with some updated statistics about, “the database associated with the English-language version of DDC 23.”
For example:
-
There are now 40,174 explicit numbers in the DDC schedules.
- Currently 29,552 mappings of DDC to LCSH (Library of Congress Subject Headings).
The complete chart with more numbers is available here.
