Learn / Copyright & ISBN
Copyright and ISBN, made simple for global authors.
These are two distinct things that get mixed up constantly — yet both matter. Here's what each one really covers and the right way to deal with them.
Copyright happens on its own
The instant you put original words on the page, copyright in that work is yours under international copyright conventions such as the Berne Convention, which is recognized across more than 180 countries. You don't have to register anything for the right to exist or to be defensible.
Filing with a national copyright office simply creates an official public record of your authorship — handy proof if you ever have to establish ownership in a dispute. Registration is inexpensive in most jurisdictions and can usually be completed online through your country's copyright authority.
An ISBN is a unique product code
An ISBN — International Standard Book Number — is a 13-digit code that pinpoints one specific edition of one specific book. The paperback gets its own, the hardcover a different one, the eBook a third, and the audiobook yet another.
Bookstores, libraries, and distributors rely on ISBNs to stock and trace titles. Skip the ISBN and your book simply won't appear in many catalogs.
Where to obtain an ISBN
Each country has its own ISBN agency, and pricing varies widely — some issue numbers at no cost, while others sell them individually or in bundles. Check the agency for the country where you're registered as a publisher.
Publish through Amazon KDP and it can hand you a free ISBN, but the publisher line tied to it will read 'Independently Published' instead of your own imprint.
Platforms like IngramSpark expect you to bring your own ISBN — so owning one keeps you free to move across distribution channels worldwide while carrying the same identifier everywhere.
Matching the right ISBN to each edition
Assign one ISBN per format: a separate number for the paperback, the hardcover, the eBook, and the audiobook.
You'll also need a fresh ISBN when you meaningfully rework the content into a new edition — but not for straightforward reprints or small fixes.
Other things worth locking down
Trademark your imprint name if you intend to release several titles under it.
Register your manuscript with a copyright office before you hand it to editors or designers if you want a clean, dated record of ownership.
Always keep an off-site backup of your manuscript — copyright won't recover files you've lost.
