What is an ISBN number? Read on to find all you need to know about ISBNs and how to copyright your book
As a self-published author, navigating the world of ISBNs and copyright is crucial to ensure your book reaches its full potential. In this post, we’ll break down what ISBNs are, why they matter, and how to protect your rights as an author.
What is an ISBN number?
An ISBN (International Standard Book Number) is a 13-digit unique identifier for your book. Each edition, format, and publisher requires a different ISBN. For example, if you’re self-publishing a paperback, a hardcover, and an ebook, you’ll need three distinct ISBNs.
While it’s not legally required to have an ISBN, not having one can limit your book’s visibility. Many retailers only stock books with ISBNs, so having one makes it easier for readers to discover your work. In the UK, you can obtain ISBNs through the Nielsen UK ISBN Store, with prices starting at £91 for one ISBN and discounts available for blocks of ISBN numbers.

The benefits of purchasing your own ISBNs
Some platforms offer free ISBNs, but these come with significant drawbacks. If you plan to sell your books across various outlets or anticipate writing more in the future, investing in your own ISBNs is worthwhile. When you register your own ISBN, you control the publisher information. Opting for Amazon’s free ISBN will label you as 'Independently Published'. Is this how you want to be labelled?
Free ISBNs from one platform cannot be used elsewhere. Each book format should have a consistent ISBN across all platforms. For example, if you use Amazon’s free ISBN for your paperback, you’ll need a separate ISBN to sell that book on other sites. By purchasing your own ISBNs, you simplify this process.
Understanding ISBN allocation
Each format of your book (eBook, paperback, hardcover) requires its own ISBN. Therefore, buying a block of ten ISBNs is a good investment, as it’s cheaper than purchasing them individually. You'll be able to publish future works without needing to buy new ISBNs each time.
When you acquire ISBNs, they are assigned to you as a publisher. If you choose not to use an imprint, you are the publisher. If you create an imprint, ensure that you enter your imprint’s name during registration.

ISBNs and Public Lending Right (PLR)
Another benefit of having an ISBN is that you can then register your book for Public Lending Right (PLR). When registered, you’ll receive a nominal payment each time your book is borrowed from a library, adding another potential revenue stream.

ISBN Know-how
Once you purchase a block of ISBNs, you’ll receive a list of numbers that you must allocate to your book formats. When you’re ready to publish, register the title of your book along with its allocated ISBN in the Nielsen Title Editor database. This links your ISBN to your book title and updates the Nielsen Book database, which is accessed by libraries, booksellers, and distributors.
It’s important to note that correcting minor errors in your manuscript doesn’t require a new ISBN, but if you significantly update your book—especially for non-fiction—a new ISBN is needed, as it will be considered a different edition.
The importance of holding your own ISBNs
To ensures that you retain all rights to your book, not just copyright, secure ISBN numbers in your name. As Cathi Poole from York Publishing Services, an experienced publishing consultant, notes, 'We often deal with Nielsen on authors’ behalfs, but we never offer ISBN numbers in our name.' Authors have had difficulties reclaiming publishing rights when their ISBNs are held by companies that have gone out of business.
When you purchase your own ISBNs, you have full control. For example, you must use a different ISBN for your paperback than for your ebook. If you choose a free ISBN from a platform, that number is locked to that platform. Your own ISBN allows you to distribute your book freely across multiple platforms.

Understanding ISBNs is essential for any self-published author. If the service you’re engaging with doesn’t mention ISBNs or is reselling them quietly as part of a package, you may not be genuinely self-publishing. Make sure you choose your own publishing name and retain control over your work.
Purchasing your own ISBNs is a straightforward process that grants you the rights and recognition you deserve as an author. As you prepare to self-publish, take these steps to ensure your book is properly registered and ready to reach your audience. Happy publishing!
