Maybe KA knows more about this, but it has something to  do  with the type
of contract you sign with the publisher.  In one type of contract I believe
you can retain control of how and where your materials are printed and in
the other you lose control to the publisher.  It is an  important area to
explore  and get legal advice if you are doing anything for publication,
whether it is print or video or audio.

My understanding was that Kathleen Huggins did not know this when  she
signed her contract and tells us all to learn from her mistake.  Sincerely,
Pat in SNJ
