A friend of mine wrote a book a few years ago, which was published by a small independent company and is now, as far as we know, out of print.
However, I recently found it on an ebook site, for sale as a download. It's not clear whether it was uploaded by the original publisher or by a Person Unknowbn.
If it's the original publisher, shouldn't they have got in touch with my friend - and shouldn't she be getting a cut of any sales? If it was someone else, should the publisher be informed and is it legal just to upload and sell an ebook that you didn't write or publish yourself?
I know that if you buy a printed book you can then sell it to someone else without having to pay the author/publisher, but an ebook is not the same thing at all.
