How to Copyright a Book: What Self-Published Authors Need to Know (2026)

Is my book automatically copyrighted?

Yes, in almost every country that matters to a self-published author. The United States, the United Kingdom, the European Union and the many other countries that belong to the Berne Convention all give copyright to an original work as soon as it is fixed in a tangible form, such as a saved manuscript file. You do not need to publish, register or add a notice for copyright to exist.

The author is normally the first owner. That means you own the book from the first draft, long before you upload it anywhere. Publishing on Amazon KDP or another store does not transfer ownership to the retailer. You grant the store a licence to sell your book, and you keep the copyright.

Copyright lasts a long time. In the US, UK and EU it generally runs for the author’s life plus 70 years, though rules differ for joint works, works made for hire and older books. Other countries use different terms, so if a market outside these matters to you, check its rules.

What does copyright protect, and what does it not?

Copyright protects your specific expression: the words you chose, the way you structured the book, your original characters as written, your original illustrations and your own photographs. Someone copying your text, or a close paraphrase of it, is infringing. Someone writing a different book on a similar theme is not.

It does not protect ideas, general plots, tropes, genres, facts, or methods. Two authors can both write an enemies-to-lovers romance or a diet book built on the same research, and neither owns the premise. Titles and short phrases are generally not protected by copyright either, although other laws, such as trade mark rules, can sometimes apply to a series name or brand.

This matters when you write too. Do not copy passages from other books, song lyrics, poems or images without permission, even if you credit the source. Quoting a short extract for commentary or criticism can be allowed under fair use or fair dealing, but the rules vary by country and are narrower than most authors assume. If in doubt, ask for permission or cut it.

Should you register your copyright?

Where there is a registration system, it is optional but useful. In the United States, you generally must have a registration (or a refusal) before you can bring an infringement lawsuit over a US work. Registering before an infringement happens, or within three months of first publication, also keeps statutory damages and attorney’s fees available. Without that, you may be limited to proving your actual losses, which for an indie author can be hard to do.

Registering within five years of publication also gives you a legal presumption that your copyright is valid and that the facts on the certificate are correct. A public record of your claim can also make takedown requests and disputes more straightforward.

Many countries, including the UK, have no official copyright registration for books. Authors there rely on automatic protection and good records: dated drafts, saved files, emails with editors and designers, and proof of first publication. One UK point to know about is legal deposit, which is a separate rule that can require publishers of printed books to supply copies to certain libraries. It has nothing to do with whether your copyright exists, so check current requirements if you publish print in the UK.

How do you register a book copyright in the US?

You apply online through the US Copyright Office. You create an account, complete the application for your work, pay the fee and upload a copy of the manuscript, or send physical copies if the work has been published in print only and the rules require it. Fees depend on the type of application. At the time of writing, the Single Author, Single Work application costs $45 and the standard application costs $65, but fees can change, so confirm on the Copyright Office website.

The single application is limited. It is for one work, by one author, who is also the claimant, and the work cannot be made for hire. If you have a co-author, an illustrator whose work is included, or you are registering on behalf of someone else, you will likely need the standard application. Register each edition that contains substantial new material, but a new cover or reformatting alone does not usually need a new registration.

You can register before or after publication, and you do not need to wait for the certificate to publish. Processing can take months. The effective date of registration is the day the Copyright Office receives a complete application, fee and copy, so apply early. Use your real legal name or your pen name in the author field, and be accurate about which parts of the book you wrote, because mistakes can cause problems later.

What goes on a copyright page?

The copyright page, usually on the back of the title page, tells readers who owns the book and what they may do with it. It is not required for copyright to exist, but it is standard in print and ebooks and is worth getting right. A typical page includes:

• A copyright notice: the © symbol, the year of first publication and your name or pen name.
• A rights statement, such as “All rights reserved”, or the terms of any permissions you grant.
• The ISBN for that edition, if you use one, plus edition information.
• A fiction disclaimer saying that characters and events are imaginary, for novels.
• Credits for cover design, editing or illustration, and any permissions for quoted material.

If you publish under a pen name, the notice can carry the pen name, though you should keep clear records of your legal identity for any registration. Our Copyright Page Generator can produce a first draft, and the guide on whether you need an ISBN explains the ISBN line. Make sure the page matches your book, for example by adding a note if you use quotations or licensed images.

How do AI, co-authors and pen names affect copyright?

Copyright is tied to human authorship. The US Copyright Office has said that material generated purely by AI, without sufficient human creative control, is not protected, while human-written text, and human selection and arrangement of AI-assisted material, can be. If you use AI in your writing, keep your own drafts and records, be ready to disclose AI-generated content when registering in the US, and remember that retailers such as Amazon KDP have their own AI disclosure rules. Rules in this area are still developing, so check current guidance.

If you write with a co-author, agree in writing who owns what, how income is split and who can license the book. Without an agreement, joint authors can end up with shared ownership and unclear rights. The same applies to freelancers. Editors normally do not own your text, but illustrators, cover designers and ghostwriters may keep rights unless your contract assigns or licenses them to you. Get the licence or assignment in writing, and check that stock images and fonts allow commercial book use.

A pen name does not change who owns the copyright. You can publish under it, and in the US you can register using it. Keep a private record linking the pen name to you, because you may need to prove ownership if there is a dispute.

What if someone copies your book, and what myths should you ignore?

Start with evidence. Take dated screenshots of the copy, save links, and gather your drafts, files and publication records. Then use the platform’s reporting process. Amazon, Apple, Kobo, Google and most sites have forms for copyright complaints, and in the US and many other places a formal takedown notice is a normal first step. Most pirate and plagiarism problems end here. If it does not, speak to a copyright lawyer. In the US, a registration is usually the key to going further, and the Copyright Claims Board offers a lower-cost route for smaller claims, though it requires a registration or a pending application.

The so-called poor man’s copyright, mailing a manuscript to yourself, gives no special legal protection. Dated drafts and cloud version history are more useful as evidence. You also do not need to fear that beta readers, editors or agents will steal your book. It is rare, your copyright exists regardless, and sharing your work is how books get better.

Another myth is that adding “copyright” text makes the difference between protected and unprotected. It does not. A notice is helpful, but protection comes from the law. Finally, remember that copyright is about copying, not coincidence. Similar books are not infringing unless one copies the other’s protected expression.
