ISBN 101 For Self-Publishers

Post image for ISBN 101 For Self-Publishers

One of the parts of book publishing that seems to confound newcomers to the field is the purpose and use of the International Standard Book Number (ISBN). Usually the ISBN appears to be the same thing as the ubiquitous Bookland EAN scannable barcode that graces the back covers of almost all books printed today.

Not only that, but since the rise of companies that perform publishing services for authors, there has been even more confusion about whether you need to own your own ISBN, whether free ISBNs from these companies are “just as good” as getting your own ISBN, and if it’s a good idea to buy ISBNs from re-sellers who offer lower prices for a single number.

Let’s review the basics of this unique identifier and explain what is so important about it, how it benefits self-publishers, and when you can safely forget about it.

Created to Solve Real-World Problems

ISBN was created as a stock-keeping identifier. Originating in the United Kingdom, the concept of a unique identifier for each version of a published book became an international standard in the 1970s.

It was created to solve a real-world problem, and it worked well. The problem was that in the pre-internet age, it was often very difficult to identify a particular book, and more so when a searcher did not have the full title, author and edition information at hand. That’s usually the case when I go searching for a book.

How would you know whether the book you are looking for is the right one? Book titles are not exclusive or protected by copyright, and it’s not unusual for several different books to have the same title. And similar titles will quickly expand the number of possibilities. Add to this the necessity of knowing which edition you are looking for—hardcover, paperback, second edition—and it’s easy to see how identification mistakes are easy to make.

With the use of the unique identifier, one that is attached to each physical format of a book, this problem is basically solved. Every title, and every different edition or format has its own unique number for tracking and search purposes.

Coincidentally the ISBN came into use at the same time that computers were becoming common, and the two were meant for each other. It’s now possible to simply enter an ISBN into a Google search bar to get all the information you need on a particular title.

Who Doesn’t Need an ISBN?

Because the ISBN is used as a basic identifier throughout the book distribution system, any book that is intended to be sold through retail channels will need to have this identifier.

There’s no absolute need for books printed for private use, or for a closed distribution to have ISBN assigned. These might include:

  • Workbooks distributed at seminars
  • Company training manuals for internal use
  • Family histories, recipe collections or other “personal” publishing projects
  • Books that will be used only as premiums, incentives or giveaways

However even publishers of these types of books might make use of this identifier if they plan to someday convert their publication to a commercial use.

Self-Publishing Hits the Scene

You may not realize this, but for many years Bowker issued ISBNs to book publishers for a nominal administrative fee.

But once the self-publishing field began to expand in response to new digital printing technology, Bowker made the process of acquiring ISBNs easier, and a lot more expensive. Now ISBNs are sold like any other commodity by Bowker and a few authorized re-sellers. And to accommodate the needs of these self-publishers, they made individual numbers available for the first time.

However, the price Bowker set for individual identifiers (currently $125) has shocked many new publishers. (You can read an explanation of why the cost is so high in the interview I did with Andy Weissberg).

But keep in mind that it’s rarely a good idea to buy just one ISBN. If you intend to issue your book as both a printed book and an ebook, you will need two ISBNs right from the start, and the cost of buying two individual numbers is the same as purchasing ten numbers (currently $250).

In addition, Bowker is actually registering your publishing company when they issue you your numbers, not your individual books. This is a key step for many self-publishers and that’s a pretty good reason to get an ISBN as well.

The Problem of the “Free” ISBN

In order to mitigate the cost and the bother of registering your company yourself, author services companies started offering “free” identifiers to clients. How were they able to do this?

Bowker’s pricing for these numbers has huge volume discounts, that’s how. For $5,000 you can acquire 5,000 ISBNs. That’s only $1 each, a price at which it’s easy to give them away, saving individual authors quite a heap of money.

And many authors have made use of this savings. You are a good candidate for a free number if:

  • You intend to publish only one book
  • You have no interest in starting a “publishing company”
  • You’re on a very tight budget

But it’s not the right solution for everyone, because ISBN performs many functions for self-publishers.

Know Your Retailers

People who help authors get started in publishing often remind them that this is a business, and should be approached as such. You are manufacturing a product intended for retail sales. In this scenario it’s important for you to know the policies of the retailers who will be selling your book.

For instance, here’s what Smashwords, the big distributor of ebooks, says about ISBN usage:

Smashwords retailers such as Apple and Sony will not accept your Smashwords book unless you have a unique e-ISBN. It is the primary digital identification number that many major online retailers use to track and catalog your books, and to report your sales back to Smashwords.

(Editor’s note: Everything at Smashwords is an e-book, but there really isn’t such a thing as an “e-ISBN”. They are all just plain old ISBNs.)

The Many Roles of a 13-Digit Number

Smashwords also points out one of the other uses of this handy number. In fact there are three main ways these numbers can be of use:

  1. Stock keeping, for inventory purposes
  2. item identification to differentiate similar editions
  3. Metadata

It’s this last benefit of ISBN you should think about when deciding whether to use them, and whether you want to go to the expense of buying your own numbers, or to accept the “free” version.

2 Reasons to Own Your Own ISBNs

Most of the self-publishers I’ve worked with are setting up their own publishing companies and funding their project in the expectation of becoming profitable. In every case I’ve advised them to buy their own ISBNs. Here’s why:

  1. The ISBN contains within it a “publisher identifier.” This enables anyone to locate the pubisher of any particular book or edition. If you use a “free” ISBN from an author services company or a subsidy publisher, that company will be identified in bibliographic databases as the publisher.
  2. Owning your own ISBNs gives you the ability to control the bibligraphic record for your book. This is an important part of your book’s metadata, and is a key component in your book being discoverable by online searchers. This has a powerful influence on your efforts to attract search engine traffic to your title.

Now there’s no reason you can’t publish your books with a “free” ISBN from a reputable company, like CreateSpace. Having their identifier on your book doesn’t have anything to do with the ownership or copyright on your work, you still have complete control over your own content.

And you can be very successful this way, too. April Hamilton originally published Indie Author and several other books that way, and enjoyed great success. But like others who have committed to making publishing their business, she has said she would now buy her own ISBNs.

Part of the reason, as Hamilton explains, is the changing marketplace:

Distribution options offered by print and digital publishing service providers increasingly require that the author/imprint be the registered owner of the ISBN.

Echoing this is this explanation from the Smashwords ISBN guide:

An ISBN helps make your book more discoverable to readers and other book buyers. The ISBN gains you free inclusion in Books in Print, the world’s largest catalog of books, which is licensed to all major search engines and thousands of bookstores and libraries. Your ISBN record will also receive a free online listing at the online Books in Print bibliographic database that’s available on the open Web at

Takeaway: If you plan to sell retail you’ll need to use ISBN. For strictly private publications, you may not need it at all. And if you plan to continue in publishing, buy your own ISBN block from the start.

If you have questions about ISBNs or how to use them, please leave a note in the comments.

    Do you use a particular company to upload your content in create space?


    Patricia September 30, 2015 at 6:41 pm

    Hi Joel,
    Great article. I have been following you for about 2 years now. You and several guests have been tremendously helpful with templates for streamlining the writing/blogging process and the book cover template/ pulp template for interior etc. So, thank you for being around and moving me forward. You are a lifeboat in this sea of self publishing!
    To clarify, you said createspace gives free ISBN and w/kindle I won’t need an ISBN. Why then do you suggest that [we] purchase a “block” of #’s?
    I have 1 book going into createspace, but plan to write 1 or 2 more. Does the “block of #’s cover multiple books?
    Thanks again.


    Kevin Wright August 31, 2015 at 9:56 am

    Here’s a potentially dumb line of questioning, but just to clarify: if I purchase my own ISBNs so that I can name myself as my own publisher, does that mean that I’d have to incorporate or otherwise create a publishing house? Or should I just use my name? Or do I essentially just create a “front” (i.e.; “Widget Publishing”) that I then use for all of my novels?

    Thank you for explaining things so very clearly…


    Stephen McDonald August 31, 2015 at 10:34 am

    You can use your own name however its better to just create your own publishing house name (something creative) that you can make your own brand and platform from. Also its look much more professional when it looks as if it’s coming from a publisher house / company and have a much better chance of selling on the market aswell. FYI there is no need to create a publishing website. But it’s recommend that you have a author website to place all of your creations.


    Joel Friedlander September 1, 2015 at 12:28 pm

    Kevin, you don’t need to incorporate but you will need to establish some kind of “business entity” since you’re now in the book publishing business. You are likely going to be a “sole proprietor” but after creating a publisher name, you’ll want to establish it in your local municipality. Here, that means filing a Fictitious Business Name statement with the county clerk.


    Michael N. Marcus September 2, 2015 at 5:40 am

    In some places you get a “DBA” (Doing Business As) certificate, not a “Fictitious Business Name statement,” and it may be provided by a city clerk, not county clerk. The cost may be a one-time charge of about five bucks, but there may be an annual fee, and you may have to advertise the new name.

    Be prepared for lots of pitches from cleaning contractors, employment agencies, insurance agents and accountants who’ll learn of your new business — even if it’s just a new name.

    Make sure your bank adds your new business name to the checking account you use for business, so you can deposit checks made out to the business. If you don’t have a separate account for the business, get one. It’s good to have a credit card or debit card in the business name, too.

    A business card (paper, not plastic) with your publishing name will give you more credibility when you meet people at conventions, trade shows and bookstores. I like VistaPrint.

    Joanne Murphy July 25, 2015 at 11:12 am

    Hi. I am currently working with a self publisher who obtained my IBSN number for me. Since the company is print on demand, my cost is so high that it will be impossible to get it into any bookstore. I am now looking to order a larger quantity and use a printing company which will reduce the price. Do I need to get another IBSN number because I will be using someone different? Thanks.


    Joel Friedlander July 27, 2015 at 10:23 am

    Joanne, what you need to do is go to and buy your own ISBNs. That way you won’t have to change ISBNs if you change printers or POD vendors.


    Liz E September 19, 2015 at 2:51 pm

    Hi love,
    Your input made me sit up and take notice. I am presently making enquiries through FastPencil, and Ingram – re. Publishing my photobook. This is not a money raiser, in fact, the ebook and iBook publishing, I have stated I would prefer to be ‘free books’ or if not possible – sold at cost; and paperback print on demand – available at cost. It is a book of Christian outreach – a pilgrimage with the help of photos. Encouragment – not Fear of God, if you get my drift.
    Hence, your comment re. the price of manufacture of Books printed on demand has turned out to be extremely expensive.
    I may be nieve, but I thought that the cost of a printed paperback (or hardback, come to that) is paid by the customer, who also pay the postal charges. Can you help me understand and come to terms with the possibility that there are hidden expences that I am presently unaware.
    Because my reason for publishing this book is not for profit – my spending limit is £200 or $299. Am I being taken for a ride in believing that these large publishing companies are actually being honest and above board?
    I’d be happy for any advice from anyone who has tread this path. Another question is – if I want to protect my photographs, and this will be my only published book – is there a cheap way of obtaining a ISBN, although it would hopefully be in two formats – Digital and print. Does that mean I need two ISBNs See what I mean, total novice !
    Blessings. Liz. X


    Joel Friedlander September 21, 2015 at 12:23 pm

    Liz, some print on demand vendors—like CreateSpace—will make an ISBN available for your print book at no cost. And if you publish your ebook to Kindle, you won’t need an ISBN at all.


    LeAnna July 23, 2015 at 1:08 pm

    Hi Joel,
    I love all the great info you share! I have a questions about ISBN’s: I designed a deck of cards that come in a nice package that my client plans to sell. She would like to sell them individually at first, but with the hopes of having a retailer or two pick them up for sale as well. I am assuming we need a barcode, do I go through the same process then as for a book isbn? Thanks i advance for your insight.


    Berni June 29, 2015 at 7:53 am

    Hi Joel
    I have just completed a children’s story and was going to putit on create a space and use their ISBN code but someone said it would be better to have my own.
    I do not write a lot of stories so it may be a couple of years if ever to write another, do you think it would be more beneficial for me to use create a space IBNS code?


    Moshe May 25, 2015 at 3:16 pm

    We service authors and would like to purchase ISBNs for them. Is there a way to buy a batch of ISBN numbers and then register each to a different author?


    Joel Friedlander May 26, 2015 at 11:44 am

    I suggest you contact Bowker directly to find out whether you can become an authorized reseller of ISBNs. ISBNs are registered with publishers, who then assign them to specific books, not authors.


    Moshe May 26, 2015 at 1:16 pm

    Will do, and thanks for a superb article.


    moshe September 19, 2015 at 3:43 pm

    Called them, and No. Its all registered to the person/company who bought it.


    Ingrid Foster May 8, 2015 at 11:17 am

    Hi Joel, great information. Thanks so much for sharing!

    Two quick questions, is it legal for me to use an IBSN bought in Australia for a book copyrighted in America?

    Also, if I am publishing a short story that will later be part of a collection, is it a problem to have more than one ISBN associated with that story? They will have two different titles.

    Thanks again,
    Ingrid Foster


    Meg April 30, 2015 at 5:16 am

    This is a great article, Joel. Thanks very much. I have some concerns though… It seems the costs of self publishing are prohibitively high when you go down the route of buying your own ISBNs! I wonder if you can offer any advice?

    I’m just about to publish an adult colouring book and would love to get into book stores. So, the natural option seems to be to use Createspace to access the Amazon marketplaces in print, and use Ingram Spark to access worldwide distribution at industry standard discounting. Sounds great, but to do this, you need your own ISBNs and barcodes – my eyes popped out of my head when I saw Bowkers prices! Are they having a laugh?!

    There’s no way, as a start up business (when I have already spent my startup budget on editing services for my next novel, seeing as we know how important that investment is!), that this is affordable. I fear that I will be ‘stuck’ on Amazon with Createspace, as it were, with one of their assigned ISBNs (and of course then no way of getting into bookstores with this particular project given CS’s insufficient discounting). If I can then afford down the line to go buy my own ISBNs to publish though Ingram Spark, there’ll still be hassle as I will presumably have to create an entire new file on Createspace – I am guessing one book is not permitted to have two different ISBNs.

    Very frustrating situation in any case.. Can you offer any advice to make buying ISBNs (and I presume barcodes too) more cost effective?


    Joel Friedlander May 1, 2015 at 12:05 pm

    Meg, it’s up to you how to use your budget. The lowest price I’ve seen for individual ISBNs is $99, and that doesn’t seem like that much money for a really necessary purchase for a publishing business startup. And if you do end up producing the book through both CreateSpace and Ingram Spark, make sure you DO use the same ISBN, since it will be the same book.


    Meg May 2, 2015 at 1:14 am

    Hi Joel,

    Thanks for the reply. :-)

    As I’m based in the UK, I can’t buy one of the 99$ ones on CS and Ingram don’t offer the service in the UK either. But to purchase 10 ISBNs in the UK via Nielson, it’s £144 which is a lot more reasonable. And, the lovely Derek Murphy of Creative Indie has a free barcode generator. So that makes it a lot more cost effective.

    Interestingly, I spoke to Createspace and they said it would be fine for me to submit on CS with their ISBN, purely for distribution through Amazon, and later down the line setup the same book but with my own ISBN with Ingram for worldwide distribution. What I’ll do is submit on CS for now and then sort out my own ISBNs and submit a revised or deluxe version on Ingram. As it’ll be a new edition, I can then resubmit to CS and get the two editions linked. I think that’s the best way around it for now…

    Thanks for your advice as ever, Joel. :-)

    I love being an indie author, but it gets complicated sometimes!


    Joel Friedlander May 4, 2015 at 11:05 am

    Yes, there are a lot of details to the process that come as something of a surprise. The only comment I would make is that I’ve always felt it’s a bad practice to issue the same book with 2 different ISBNs. It defeats the purpose of having a “unique identifier” for each edition of the book, and can be the source of confusion both for distribution partners and buyers. Good luck!


    illyanna Maisonet (@EatGordaEat) April 23, 2015 at 11:35 pm

    Dear Joe,

    I have gone through most of the Q+A on here and there’s nothing about cookbooks. With the funds I raised through Kickstarter, I am finally sending my cookbook to the printers. Yes, it is a book, but it’s more of a manuscript to send in to publishers. I’m hoping it’ll give me leverage for a much larger (and more traditional looking) cookbook. I know you told Ed Dugan in an above comment that if authors plan on publishing numerous books, it’s wise to buy the ISBN. But, I don’t even know if what I’m doing with this book is considered “publishing.” To me, it’s just a small cookbook/manuscript that will go out to KS contributors and publishers.

    I’d also like to be able to sell it online, if I can. With that being said, does it need an ISBN?


    Joel Friedlander April 24, 2015 at 11:39 am

    illyanna, there’s no mention of cookbooks, or of any other specific kinds of books because, for ISBNs, it really doesn’t matter what the book is about. An ISBN is simply a unique number that identifies a specific edition of a particular book. If you want to sell your book through retail channels (online or offline), you will need an ISBN. If you don’t, you won’t.


    illyanna Maisonet (@EatGordaEat) April 24, 2015 at 10:56 pm

    Very concise, got it. Thanks!


    illyanna Maisonet (@EatGordaEat) April 24, 2015 at 10:58 pm

    Wait! Just one more question, please. Should I use a free ISBN through CreateSpace for this first book, and then purchase one for my larger book down the road?


    illyanna Maisonet (@EatGordaEat) May 1, 2015 at 6:21 pm


    Cynthia Henry April 23, 2015 at 1:16 pm

    Wow – there is a lot of information. As a person who is still in the process, I have not acquired my ISBN’s yet. Now, I am totally confused. Along with the ISBN’s I understand you also have to purchase the bar codes separately. Being on a budget, is there a way to get a package deal? I was considering Xlibris, they have been seriously stalking me. Now that I have read everyone’s comments, I think I want to get my own ISBN’s. But, no one has mentioned the bar codes.


    Joel Friedlander April 23, 2015 at 2:00 pm

    Cynthia, you might want to take a look at this article before you sign with anyone: Subsidy Publishing: Proceed With Caution.

    Don’t worry about the barcode, and don’t spend any money on it. If you are using a book designer or cover designer to help get your files ready, they will likely be able to supply one at no cost to you.


    Author Annie Mitchell April 14, 2015 at 3:17 am

    if you have isbn on your paperback differnet from your kindle isbn
    and the kindle isbn does not search in google why is it there do you know ?
    someone else set this up for me thanks


    ed dugan April 9, 2015 at 8:22 am

    My current website is simply a temporary “parking lot” for by books. Another one is in the works. We are moving in the direction of protecting a series of titles with a U. S. Trademark and it seems my best bet is to own my ISBN since I assume we would be considered as the publisher. That seems to be true even if we use CreateSpace, which is our plan. Any comment or suggestions.


    Joel Friedlander April 9, 2015 at 11:01 am

    ed, the ISBN has nothing to do with your website or trademark issues, but in general, and especially for authors who plan to publish numerous books and distribute them widely, you would be wise to acquire your own ISBNs and maintain your own listings for both your publishing company and book titles at Bowker.


    Justin April 3, 2015 at 12:23 pm

    First: Thanks for being here. I read your stuff all the time and I find it insanely helpful.

    Second: Can a first edition of a book be published with, say, CreateSpace’s ISBN or their imprint option and then a later edition be created using an ISBN I purchased?


    Joel Friedlander April 3, 2015 at 5:12 pm


    Sure. A new edition is commonly assumed to have at least 10% of the content of the book changed in some way, or major additions made to it. You could even publish the new edition, under your own ISBN, with CreateSpace.


    Justin April 5, 2015 at 10:11 am

    Thank you very much.


    shery March 2, 2015 at 8:45 pm

    Hi Joel,

    I am a reseacher and I live in another country, I have published my first book as a self-publisher with a ISBN and copyright in my country. With a american friend’s help, I did the translation for english and spanish version, and I am intending to send these books for many institutions around the world as a strategy to promote the animal conservancy program. So could you help me telling what kind of register shoud I get to release it in USA?


    Felipe February 26, 2015 at 12:52 pm

    I’ve seen some companies with more affordable options for ISBN than Bowker. Anyone know if Publisher Servces ( is reliable? Or should I use Bowker?



    Felipe February 26, 2015 at 12:52 pm

    I’ve seen some companies with more affordable options for ISDN than Bowker. Anyone know if Publisher Servces ( is reliable? Or should I use Bowker?



    Joel Friedlander February 27, 2015 at 10:15 am

    Felipe, they are an authorized agent for Bowker, so there’s no problem using them. Keep in mind that their lower-priced options, although perfectly fine for “hobbyist” publishers, will not show you as the publisher of your book, and many of the “extras” they offer are largely irrelevant for most authors.


    Susie February 19, 2015 at 9:05 am

    I’m getting ready to self-publish 2 books that will be for retail, so I understand I need ISBN #s.
    Is the least expensive way to do this through Bowker, knowing that I don’t want to go back and redo or add something else having to do with ISBNs should my products want to be bought by a zillion people?


    Tammy January 25, 2015 at 4:26 pm

    If I buy an IBSN number, can I use it on both for the Smashbooks e-book and the amazon kindle E-book? I figure that they are both e-books, so it’s the same thing just in different places.

    Please let me know, because I’m really confused about how this all works.


    Joel Friedlander February 20, 2015 at 11:18 am

    Tammy, they ePub and Mobi/KF8 (Kindle) formats are different editions and each needs its own unique ISBN.


    Khadijah Shabazz December 24, 2014 at 2:42 pm

    I am very motivated to get my self-publishing company up and running. I have been doing a lot of research which has me at this point in obtaining a ISBN number. So when I register my ISBN number will that stop another company from using my name? The reason I’m asking is because although I have a DBA in my state it doesn’t cover the whole country. Please advise, thank you for your wonderful service!



    Diana Forrest November 24, 2014 at 11:05 pm

    Hello, I publised my partners book in 2012, and now have 9 left, are they still valid, and as I want to publish my own book, can I use one of his numbers. Also if music or film is added to the book (created by me) is that alright.
    Thank you very much


    Joel Friedlander November 25, 2014 at 11:58 am

    Diana, the ISBNs don’t expire. In fact, I’m still using the ones I was issued in the 1980s. You can add whatever you like to your book, that’s up to you.


    Claire Prengaman November 24, 2014 at 5:13 am

    My husband wrote a book when he was nineteen and had it published through xlibris (BIG mistake). Anyway, we have canceled the services with them and have the manuscript and want to edit and revise the book. We would be changing grammar, dialogue, and maybe adding some subplot. It already has an ISBN number, is copyrighted, and is registered with the Library of Congress. If we make these changes, will we need to get new ISBN numbers?




    Joel Friedlander November 24, 2014 at 10:03 am

    Claire, you will need a new ISBN in any event since the book will have a new publisher, and the previous ISBN belongs to xLibris. This means that your publication will be a “new edition” therefore requiring a new ISBN. You’ll also want to register a new copyright since you are adding content to the book. Good luck!


    James Jean-Pierre November 6, 2014 at 8:15 am

    Great post Joel, that’s the reason i’m doing self publishing is to maintain control of certain things. But I wasn’t sure if you have anything about taxing for self publisher or LLC’s.


    Alli October 31, 2014 at 10:34 am

    Great article! I learned so much. Any advice on how to get one?


    China October 30, 2014 at 8:54 pm

    I am a new self published children’s author. I want to sell my book through ingram and I am looking into ISBNs. I am on a tight budget, but I plan on making more books. Are there other places to buy ISBNS that might be more affordable besides Bowker, what are the advantages of using bowker as opposed to other Sites that sell isbns?
    I hope that was clear, thanks.


    StephenMcDonald December 7, 2014 at 5:20 pm

    Broker is the number one source of ISBN 10-ISBN for about $200 but completely worth it,
    Amazon will give you free ISBN numbers if or when you publish with them


    Wendy Ice October 26, 2014 at 4:58 am

    Great article Joel. Thanks. Quick question. We are offering a first edition of a book that will come in different forms (some signed and numbered). The book itself is identical, but numbers 1-25 come with an original drawing, numbers 26-100 come with three giclée prints, and numbers 101-500 come with one giclée print. Then the remainder of the edition stands alone. Should we describe each version on the copyright page with an isbn for each? All of the numbered books are already pre-sold so we don’t need bar codes, but I’m guessing we’ll need a bar code for the rest of the edition which will be available on Amazon. I’m guessing maybe we need several ISBN’s but just the one bar code. Is that correct?

    My small press is getting ready to release its second book. The previous book (and ISBN) was issued about 15 years ago by the previous author/owner. He gave us the publishing company – tiny as it was – to us when he retired. His book was small and paperback. Our upcoming release ( is hardbound and 288 pages. Could I (should I?) use his publishing company name and the publisher prefix of the ISBN for this, the second book? How do I go about explaining that to Bowker when I order? Or should we just start over with a new name and a totally unique ISBN? These are 10-digit ISBNs from 1997.

    Hello Mr. Joel,
    I hope you are okay. I enjoyed reading your article, but I still do not know what I should do to have one IBSN for my book. I cannot buy any ISBN in Mozambique but I can register my book in Mozambique. Can you please help me?

    Great article but I am still confused about buying my own ISBN # or getting the custom one from Create Space where I can have my own imprint.

    Also, if I get the ISBN # from Create Space do I need additional numbers for Kindle & PDF version?

    Thank you, Judy

    Excellent ISBN primer, Joel. I am trying to get a translated version of my book printed in my native country. From my research, each country has a different agency that gives out ISBNs. Do I need to get a local ISBN or can I use a US ISBN for printing in-country?

    Joel, I have an usual situation. I had contacted a woman who had a subsidy press. She provided the cover and book layout for a set fee, as well as the contact with Lightning Source printing. She provided the ISBN. Mid-publication she died and my book did come out. The new owners now want a huge 50% royalty on all sales, even though I paid market value for all those services plus I paid other contractors for editing and promotional materials. They have not paid anything. I have not signed a contract and asked them for my final PDF so I could have a Kindle format done by someone I have used before. Instead, they gave me a PDF for my kindle designer with a new assigned ISBN (different from my paperback of course). My dilemma is that I do not want to enter into a contract with them, and I want to receive all the royalties from the kindle version.

    My questions are 1. If I go forward and use the PDF they gave me, convert it to a kindle format and upload it to Amazon and Smashwords, do they get a cut of the royalties from these sites because its their ISBN?

    and 2. If #1 means the publisher gets a cut, can I remove their already assigned ISBN and insert a new one. Thanks. I feel in a real bind here.

    Hi Joel,
    Great article! I am helping a Canadian author friend become self-published. He has registered for an ISBN and he has a consulting company that relates to the content of his book. Can his consulting company be the publisher or does he need to establish a separate LLC to serve as the publisher? I saw where you stated earlier that “leaving you as a self-published author without a publishing company, (is) a bit of an oddity.” I’ve heard that self-published authors do just publish under their own names, but I am having difficulty verifying this. What would the pros and cons be?

    Many thanks!


    Joel Friedlander August 18, 2014 at 2:26 pm

    Meredith, it’s preferable if you plan to continue publishing to have an imprint or publishing company name, and there’s no reason not to use his existing business structure to do that.


    Dana Woodard July 22, 2014 at 9:07 pm

    If you’re in Canada, you can get your own ISBN for free. Just apply at

    …I love my country!


    Edward Tilley March 23, 2015 at 2:21 am

    Thanks so much for your note and link Dana. I had no idea that free ISBN numbers were available for us.


    Dear Joel July 14, 2014 at 6:16 am

    Great, clear article, Joel!

    So tell me if I got you right. If someone wants to write and self-publish an anonymous book and sell it anonymously on the Internet, then she should not get herself an ISBN, because that would identify her as the publisher and also the country where she lives. Right?


    Joel Friedlander May 25, 2014 at 2:37 pm

    Each separate book within the series will need its own ISBN. The only exception would be if you will only ever sell the entire set together, as one item, but even then I don’t think it’s a good idea because the books will get separated from the set eventually.


    Pretty May 5, 2014 at 2:04 pm

    I am still in the process of working through my book and finalizing the printing press to print my book. I will be marketing my book by myself , So I will be using my name as Publisher when purchasing ISBN?


    Dean April 29, 2014 at 1:46 pm

    I’m doing POD through LS, and have my own ISBNs. My book was written in American English, because that’s where I live. But I am also doing a version for UK/Australian/NZ markets, with “correct” spelling and punctuation. Do you think I need different ISBNs?


    Alex April 13, 2014 at 11:02 pm

    Hello, thanks for the article, i’ve asked specific question in another thread, but here i want to clarify: for me as the author, it doesn’t matter if my book is printed by a “publisher” company or “self-publisher” company, because it’s still will be shown as a company that published my book with my name and title on it? And the only difference is in the listings that the book was published by a company?


    Wendy Anderson April 11, 2014 at 12:55 am

    Thank you for the info; I am real new like, just; I have a manuscript with First Editing currently to be made “Perfect” and am trying to sort out my steps from here! Appreciate any comments thanks. 1. There’s BoobkBaby for an e book and maybe print book option? Then Maybe Smiths publicity deal for Book/fair/Trade 29th May New York; a book as physical presence and a listing in the catalogue. I am doing it cheap so I guess I accept an Isbn from BookBaby? What I don’t know is can you then sell your book elsewhere if they are your publisher’s and I am finding it difficult to get info and are now wondering if to consider Create Space for print book/ self publishing and or Smashwords for e book, as these guys are on the good list of publisher’s I found? Help would be appreciated please; it’s a mine field out there for the uninitiated. My true story fits in the inspirational/religious niche, full of drama and funnies and miracles and I am intending to write another true story too. I am not a writer/ maybe one day! Wendy Anderson


    Bill March 30, 2014 at 10:40 am

    I just went to Bowkers, last time I looked it was $250 for ten, which I think was not very long ago, today it is $295 for ten. Nice business model. Now $29.50 per book.
    Is there any disadvantage of starting out with a free IBSN on Creative Space and when you are ready to launch your second book, buying your ISBNs and assigning them to your original book as well as your new book?
    My intention is to continue to pursue a traditional publisher. My first book A Signal Waves is on Kindle/Amazon and I have finally gotten the cover work done for the paper copy, LOL, so now I am sitting her thinking whether I should hold off on the IBSNs until both books are on Kindle and my second one ready for print. Five months out on the second one. I want to write a little article on a couple of writers blogs that I participate on as well as my own author’s web site about this experience, so I have read through these comments and everything here seems to point to just holding your nose and paying the increasing tariff, $29.50 per book…
    Can you summarize any down side to that?
    Thanks, great discussion, Bill


    Danielle Bernock March 17, 2014 at 10:54 am

    I am working on the final things for my book to be published. Have you heard of ?
    They have ISBN’s for less ($18.99 and $99.99) but that makes me suspicious. Can you advise on this company?


    Joel Friedlander March 17, 2014 at 11:59 am

    Yes, the cheap ISBNs will show their company as the publisher of your book. The $99 version is a regular ISBN, but the company will do all the data entry at Bowker on your behalf. To take control of your own ISBNs and the metadata being entered about your publishing company and your books, (and if you plan to keep publishing) I advise you go to and open an account for your publishing company and buy the 10-pack of ISBNs for $250, dropping the price for individual, owned-by-you ISBNs to $25 each.


    AVS March 15, 2014 at 9:35 am

    I am ready to self-publish a book and think it’s wise to buy my on ISBN. Does this require that I officially register and create my own publishing company? I’m ready to promote and market this book for the long haul but I’m not sure I will self-publish again( I will try the traditional route for subsequent works) and do not plan on publishing for other authors.


    John March 27, 2014 at 11:14 pm

    Good articles are hard to find. At least until now. Yours is a uiqnue article with a lot of original thought and well-researched information. Thank you for your vast insight.


    Ronald Walker January 23, 2014 at 10:56 am

    I have several novels ready to publish in Word format but need help with cover .. Do you have recommendations for new authors?


    Joel Friedlander January 23, 2014 at 4:11 pm

    Ronald, check out the dozens of cover designers and their work featured in our monthly ebook cover design awards


    Jake Fratkin January 7, 2014 at 11:46 am

    Joel – thank you for your information. I registered for an ISBN 12 years ago, and received a bunch of numbers to I could publish subsequent books under my main ISBN group-number. How can I find out what those other numbers are? Thanks.

    Jeremy November 25, 2013 at 5:06 pm

    Hi Joel. I have a question about registering my ISBNs. I’ve established an LLC in home state as well as registered an assumed name under which my publishing company will operate. But at, to register the ISBNs I will purchase for my book, I have to create an account, and to create an account, you have to search for and click your publishing company name. But my company name not surprisingly doesn’t appear! How do I get Bowkerlink to index my company name so I can create an account to register my ISBNs?


    Joel Friedlander January 7, 2014 at 12:08 pm

    Jeremy, when you set up your account originally you enter your publisher name at that point. Then, when you go to register the ISBNs the company name you registered with Bowker (not with your local agency) should be on their list.


    Jeremy January 8, 2014 at 12:54 pm

    Thanks, Joel! I figured that was how it worked, but it’s comforting to get confirmation before going through the payment process and shelling out the $250. Much appreciated! Now onward with my publishing adventure…


    Azlan March 27, 2014 at 8:48 pm
