To me it's curious that one can scan a paper book (their own copy, presumably) and turn it into an ebook and not breach copyright.
Why curious .... well with all the who har about copyright and ebooks I thought this also would have been outlawed.
So common sense prevails in some quarters of the ebook copyright discussion.
Of course, I'm presupposing this is the case irrespective of copyright status - that is in or out of copyright.
