I'm at Albany Law School Library, with a couple of thousand periodicals.
We use Hein in Buffalo, NY.  They seem to be small enough to have
real human beings answering questions, but seem to know what they're
doing.
   I deal with the serials control side of things, not acquisitions.
If you want more details about how Hein deals with the purchase and
invoice aspects, send a message to my boss, Elizabeth Duncan,
Head of Technical Services,  ldunc@mail.als.edu
