A very helpful and, I believe, complete list is available from Kevin
McElhone for under $20, if I recall correctly.  It includes a brief
history as well.  You may contact him at:

  Kevin McElhone
  47 St. John's Road
  Kettering, Northants NN15 5AY
  ENGLAND
  phone: 1536-523988
  fax: 1536-519813

Another VERY knowledgeable reference is:

  Richard Dutton
  16 Bloomfield Way
  Llewllyn Park
  West Orange, NJ 07052
  (201)669-4783

Richard is quite capable of recognizing most tunes by ear (if you have
lost labels), and has a VERY extensive collection.  He would also be
interested in trades of cobs as well.

If you would like any information that I can offer from my personal
references, or would like clarification of any titles from my copy of
Kevin's list, just let me know!
