I just received this email from Amazon regarding the sale of my books as eBooks on their site. It's all Ingram's fault (isn't that always the case?):
Greetings from Amazon.com.
Thank you for contacting Amazon.com regarding these ebook listings.
We recently received incorrect data from Ingram, Amazon.com's sole
supplier of ebooks which may concern the items mentioned below. Due
to a technical glitch, a number of false ebook records were added to
the Amazon.com site temporarily. However, these listings are now
in the process of being removed, and will no longer appear on our
site within the next 2-3 days. Please accept our apologies for any
inconvenience you may have experienced due to this error.
Please don't hesitate to contact us again should you have any
further questions, and thanks for your interest in Amazon.com.
