I would give the opposite advice. LCC will have fewer pre-composed
headings than LCSH at id.loc.gov, and the terminology associated with
the numbers in digital LCC will be less user-centric than the LCSH
subject headings. cf my most recent blog post:
http://kcoyle.blogspot.com/2011/10/relativ-index.html
There isn't any entry vocabulary for users other than LCSH -- which
isn't really entry vocabulary to LCC and is definitely NOT entry
vocabulary to DDC.
