Allen Konigsberg long ago published a book "The Patent History of the
Phonograph 1877-1922". The work has been done thru 1922 at least. As I
typed this, I realized that I do not have a copy of it, so BEFORE
sending this out I checked Amazon -- I immediately got the $25.00 copy,
leaving the $150.00 and $500.04 copies. I don't see it in Nauck's.
Unless Allen has some copies left -- there were only 1000 -- it now is
an expensive book. But the field is wide open to update the material
beyond 1922.

Several years ago, for a course I was teaching, I compiled a folder of
audio patents. Not everything, but some things that were important for
the class to see. I have to run off to class now, but I'll post a list
tonight.
