The University of Michigan maintains what we call “High Level Browse” — a
mapping of LC/Dewey call numbers to a limited hierarchy, based loosely
around academic departments (at least at the time it started). It’s still
maintained, and may prove generally useful as well.
The HLB hierarchy <http://www.lib.umich.edu/browse> gives you an idea of
what it is, and you can download and XML dump of the categories and their
associated call number ranges
if that’s your thing.
