Hi. I changed the NYTimes login because, well, the old one stopped working. Sorry about lack of topicality lately, I’m experiencing a renaissance of love for classification schemes since I now work in a library and don’t know DDC.
Then there’s the Weine System, an adaptation of the DDC for Judaica. See also David Elazar’s Classification for Libraries of Judaica. Dewey, sometimes accused of anti-semitism, files all Jewish books under 296.
