The ISBN is what identifies the publisher as the publisher. If you do not own the ISBN you are not the publisher. If you are not the publisher, you are not a self publisher… it is as easy as that!
Chapter 3: ISBN and the importance of Ownership
OK, I get asked the question about, you know, “When do I need to use a new ISBN for the same book?” And I talked about like my publishing basics book. It’s in its fifth edition. Well, every one of these editions has a new ISBN because it’s a new edition.
As far as your ISBN, I’ve been asked a question. You know, “I’m from Canada. Can I buy an ISBN through you?” The answer’s no. I mean you buy your ISBN. Every country has an agency that’s responsible for that country and it’s a simple Google search.
When you look at what’s going on now, today with the ebooks, OK, especially, you need a different ISBN for each one. So you’ve got a paperback book, ISBN 1. You’ve got an ebook, that’s a mobi which is on Amazon, ISBN 2. You got an ebook which is an epub, which is like everybody buy on Amazon, that’s an ISBN 3. So the minimum I would say, now, is to buy 10.
There’s an agency for every country that’s assigned the task of assigning ISBNs to publishers. In the US, that agency is R. R. Bowker.
