@nopatience I didn't buy any ebooks in any form myself so I don't really know what I'm talking about here, but I remember someone (maybe it was @karlemilnikka ) saying that the thing to do is to buy e-books in a way that makes it possible for you to download book files in an open format (possibly with some watermarking thing to discourage you from spreadig it to others) so that you know you will always be able to read the book. Even if the company that sold it disappears in the future. @mwl
