I am about to obtain some ISBNs for a few books I plan to publish as an eBook and possibly in print.
From books I have bought from major publishers, I gather that the eBook and print version have separate ISBNs. I also gather that a new edition of a book would require a new ISBN.
If I publish a correction to either the print or ebook version, would that require a new ISBN? What if this results in a change of page numbers? Or the insertion/removal of paragraphs or whole chapters?
The question is, at what point are the changes sufficient to warrant a new ISBN?
