Earlier Classification Systems
I have done some recent web searching on some 'library classification

SUO (Standard Upper Ontology). I thought other list-members might
benefit from a synopsis of some of what I've found.
Some of this was found at

Thomas Jefferson, whose personal library became the core of the Library of
Congress, arranged his books into three types of knowledge, corresponding to
three faculties of the mind: Memory (History), Reason (Philosophy/Science),
and Imagination (Fine Arts).
