Why it’s essential for authors to own your ISBNs
Be free! Own your own ISBNs
If you are an independently published author who wants to self-publish professionally, you absolutely must buy your own ISBNs. This post will show you the many reasons why you should invest in this for your independent author-publisher business.
First of all, an ISBN is an International Standard Book Identifier purchased in the country you do business in. In the USA we get them from Bowker, which is owned by ProQuest, a private company, and they're expensive. In other countries, ISNBs are issued by government funded entities like libraries, so they're free (thanks to taxpayer dollars). Find your ISBN agency at the International ISBN Agency website.
The key word is "professionalism"
If you care about how the industry views you as an author and a publisher you will adhere to professional standards. Your book should look like and be distributed like any book published by the traditional publishing houses. That includes your own ISBNs under your own publisher name, professional cover and interior design, a CIP block and ISBN and price embedded in the barcode. See the IBPA's Industry Standards Checklist for a Professionally Published Book.
A CIP (Cataloging in Publication) block is necessary for two reasons. First, to make your book indiscernible from any other professionally published book. But mostly it's to make your book attractive to libraries, and this is not an insignificant market.
Your CIP block is listed on your copyright page and, like the old Dewey Decimal system, it gives librarians the information they need to shelve your book.
Selling to libraries requires that you obtain an LCCN and a CIP block for your book. To get a CIP block you need a Publisher ID. (That's the 7525 part in the example ISBN shown.) Your unique Publisher ID is embedded in the ISBN (packs of 10 and up). Library sales are not a trivial market!
Future-proof your book
In the future, you may want to partner with a small press or make some kind of hybrid publishing deal. These professionals will evaluate how easy or how difficult it is to manage your book data and get it on over to their catalog before they make a decision.
When you control your book data - that is, when you own your ISBNs - you can access your ISBN records and "forward" your old ISBNs over to the new publishing company.
Will Amazon, IngramSpark, Draft2Digital, StreetLib, and other good distributors do that? No, certainly not. So you may have a much longer period of transition where the "old" version of your book is out of print and the industry does not know that it's available under a new ISBN.
You'll never be trapped with a vanity press
A "free" ISBN is never free. It comes with a price. I've helped many authors extricate themselves from vanity presses who own their book data, to take back their freedom to choose where they will publish their book.
Among those named in Writer Beware, a watchdog list, are all of the Author Solutions companies (Xlibris, iUniverse, Author House, Balboa, to name a few), Outskirts Press, and Tate Publishing.
Ethical self-publishing companies will always allow you to apply your own ISBNs. Unethical self-publishing companies often force you to accept them as the publisher.
So purchase your own ISBNs and you'll never be trapped with an unscrupulous author services company who charges much too much for services and printing.

One format + two ISBNs = confusion
When you use an Amazon ISBN for your book and then want to distribute it more widely, your ISBN will not transfer to IngramSpark, PublishDrive, Draft2Digital, Smashwords, or elsewhere. That ISBN is owned by Amazon. So if you've done that, and now you want to own your own ISBN for your book, you have several options:
- 1Continue using the distribution company's (Amazon's) free ISBN for your book and then..
- 2Purchase your own ISBNs and apply one of them to the book that's being distributed with the new company. This results in one book (paperback) with two ISBNs, which is not ideal, but if you...
- 3Purchase your own ISBNs and retire and replace the Amazon ISBN, creating a single ISBN for that format, you may be some interuption and redirection that makes your book unavailable for a while. If you book is not experiencing many sales this is okay, but if you've got a bestseller on your hands, it's probably best to stick with solution 2 above.
If your book has two ISBNs you may be missing out on bestseller status. The industry counts book sales by formats. So if you've sold 2500 ebooks on Amazon and 500 ebooks on Kobo under two different ISBNs, and 3000 is the magic number to be considered a bestseller in your category, you won't get that publicity because the industry simply won't know.
Bookstores don't like Amazon
You should be friends with your local independent bookstore. Want to do a reading there? An Amazon brand on your book is not good for making friends with them.
Translated versions of your book
You'll need a new ISBN to identify your Spanish language paperback, your German language paperback, your French language paperback. Your Spanish language EPUB, your German language EPUB, your French language EPUB... are you getting it?
Why miss out on foreign sales? You can do this easily and for free with StreetLib and Bablecube, sharing the royalties with the translator.

Which book formats need their own ISBN?
You'll need one ISBN for your hardback, another for your paperback, and stilla another for your ebook. If you create an audiobook, that's a fourth ISBN. It doesn't matter where you distribute - it's the format that counts.
- 1Paperback: Your paperback printed and distributed by Amazon KDP to the Amazon store should have the same ISBN as the one you upload to B&N or IngramSpark. If you got a free ISBN from CreateSpace... well, that was a mistake, so just keep it and apply your own ISBN to the book you upload to IngramSpark or elsewhere.
- 2Hardcover: No matter where you print and distribute your hardcover book - if you create one - you'll use the same ISBN for that, too. (I recommend IngramSpark for hardback book creation and distribution.)
- 3EPUB: When you distribute your ebook to Amazon using a distributor (popular choices include IngramSpark, Smashwords, PublishDrive, Draft2Digital, StreetLib, Bublish, Gatekeeper Press) you'll need just one ISBN for the EPUB version. That EPUB will be sent to Amazon, who will create a Kindle file from it. That's why you do not need a separate Kindle ISBN.
- 4Kindle: If you upload your ebook to Amazon KDP directly, you'll need a separate ISBN for the Kindle (MOBI) edition. If you're distributing your ebooks directly from your website using an e-commerce system like PayPal or Gumroad you definitely should use different ISBNs for the different formats.
- 5Audiobook: Another ISBN gets assigned to the audio edition of your book, too.
- 6Special editions: If you create a special, custom edition of your book with images, links, multimedia, etc., that's one more!
- 7Repeat the above for every language your book is translated in.
How to purchase your ISBNs
In the US, authors should go to the Bowker My Identifiers site and sign up for an account. Buy 10 ISBNs for $295 or 100 for $575. It costs $125 for one, and you'll need two or three for the various formats. (More on that down the page.)
In the United States, ISBNs are expensive. In Canada, they're free. Use your search engine to find your country's ISBN registrar.
