How Do You Classify Everything?

- Dewey Decimal Classification (DDC) (old library system, mostly US/Western)

Alternatives:
- Comparison of Dewey and Library of Congress subject classification (old, mainly US)
- Universal Decimal Classification (old, but perhaps better than dewey)
- Colon classification (old but interesting because facets)
- Bliss bibliographic classification (old, UK, books, more facets than colon)
- BSO - Broad System of Ordering (modern?)

# todo:
- more research, google scholar
- alternative ideas based on abstract/mathematical/universal facets
- binary trees?
