So no, they cannot shift between formats.
Oh hardback usually starts with 1 and paper with 13
An ISBN certainly should be unique to a particular format, but some cheapskate ebook authors use the same ISBN for different ebook formats (e.g. the same ISBN for an ePub and Kindle edition of their book). This isn't in accordance with the way that ISBN's are designed to be used, but there aren't any "ISBN police" to enforce it .
