Hello everybody. This is my first post here, so please accept my apologies for any breaches of forum etiquette.

So let's start. I have bought a lot of eBooks and many come with DRM. Although I'm not especially keen on DRM, I /do/ understand that publishers would like to prevent unauthorised copying of their content.

However, I would also like a measure of reassurance and I'm not absolutely sure that common types of DRM provide it. More specifically, I would like to know that the books I buy are genuine publisher authorised copies. How can I establish that this is the case?

Please note that I only buy eBooks from booksellers that are, as far as I know, reputable. But there is an element of trust involved. Suppose, for the sake of argunent, that unauthorised copies end up being distributed by the bookseller, either on purpose or by accident. It's clearly important for both the publisher and book buyer that this doesn't happen. How can I know this is indeed not happening?

Thank you!
