You must problem a individual ISBN for each version of the book and for every structure. For example, if you issued the exact same guide to be a print e-book, e-guide, audio e book and Braille reserve, you'd probably demand a individual identifier for each. If just one yr later, you up-to-date the manuscript and re-issued the e book, you would probably assign new ISBNs to this second edition in Just about every of its unique formats.
