ClassificationWeb also doesn't give machine-processable mapping files
(for LCC/Dewey/LCSH 'crosswalks'), so far as I know, it only gives you a
web interface for humans to look at the mappings.

To implement the kind of interfaces we are imagining, we _need_ an
affordable source of _machine readable/processable_ 'authority' data,
including the information actually found in LC authority records, as
well as 'value added' things like the LCC/Dewey mappings that I believe
OCLC is the originator of.
