A very important source of information is the journal of the Musical
Box Society International, "Mechanical Music".  Over the past years
several articles on Thorens disc players have been published by me and
Hendrick Strengers.  Since the MBSI journal is not available on-line
yet, I sent the original requestor via email these four articles
published in that journal:

Shaw, Brian E.:  "A Discography of Thorens 4.5 Inch Format Discs",
  Journal of Mechanical Music, Autumn 2000.

Strengers, Hendrick H.:  "Thorens 4.5 Inch (11.5 cm) Discs For
  30 Teeth Combs", Journal of Mechanical Music, Spring 2001.

Strengers, Hendrick H.:  "The History of Thorens",
  Journal of Mechanical Music, Spring 2001.

Shaw, Brian E.:  "Thorens, Inc. versus the United States Government",
  Journal of Mechanical Music, Autumn 2005.
