Hi Patrick,

Over the last few weeks I've been doing something very similar.  I was able
to figure out a process that works using OpenRefine.  It works by searching
the VIAF API first, limiting results to anything that is a corporate name
and has an LC source authority.  OpenRefine then extracts the LCCN and puts
that through the LCNAF API that OCLC has to get the name.  I had to use
VIAF for the initial name search because for some reason the LCNAF API
doesn't really handle corporate names as search terms very well, but works
with the LCCN just fine (there is the possibility that I'm just doing
something wrong, and if that's the case, anyone on the list can feel free
to correct me).  In the end, you get the LC name authority that corresponds
to your search term and a link to the authority on the LC Authorities

Anyway,  The process is fairly simple to run (just prepare an Excel
spreadsheet and paste JSON commands into OpenRefine).  The only reservation
is that I don't think it will run all 40,000 of your names at once.  I've
been using it to run 300-400 names at a time.  That said, I'd be happy to
share what I did with you if you'd like to try it out.  I have some
instructions written up in a Word doc, and the JSON script is in a text
file, so just email me off list and I can send them to you.
