In reply to Tom Hinders:

Dear Tom et al,

I contacted IPD just recently at the below address:

  Int'l Publishers Distributor, Inc.
  820 Town Center Drive
  Langhorne, PA  19047
  Phone: 215 750 2642
  Fax  : 215 750 6343

I almost replied directly, but then I thought of all those frustrated
librarians who might also be looking for answers.  I hope that you are
able to find them.

I hope to have been of help...
