How to Copyright a Book: Step-by-Step Guide for Authors

In most countries, your book is protected by copyright the moment you write it down. You don't have to file anything or pay anyone. Some countries, including the United States, also offer optional registration, which gives you extra legal advantages if you ever need to enforce your rights.

This guide explains what to do, in order, from confirming your automatic protection to registering, adding a copyright notice, and keeping records. It is general information, not legal advice. If you have a dispute, a complicated co-authorship, or a large commercial deal, talk to an intellectual property lawyer in your country.

What you need before you start

Have these ready:

• A finished or near-finished manuscript in a fixed form, such as a DOCX, PDF or EPUB file. Copyright protects expression that has been written down, not ideas in your head.
• Your legal name and the name you publish under, if you use a pen name.
• A list of anything in the book you didn't create yourself. That includes quotes, song lyrics, images, licensed material, contributions from co-authors, and AI-generated text.
• Your publication status and date, if the book is already out.
• Your country of residence and where you'll publish. This decides which registration options exist.

If you're unsure what the term covers, the glossary entry on copyright has a short definition.

Step 1: Confirm your book is already copyrighted

As long as you wrote it yourself, it almost certainly is.

Most countries belong to the Berne Convention, an international treaty. Under it, copyright arises automatically when an original work is created and fixed in some form. Registration, a notice, or a filing is not a condition of protection. A manuscript saved on your laptop is protected the same way as a printed book.

Copyright protects:

• Your actual words, sentences and the way you've arranged them
• Original characters as you've written them, in many cases
• The selection and arrangement of material, such as the order of recipes in a cookbook

Copyright does not protect:

• Ideas, plots in general terms, or genre conventions
• Titles and short phrases (these sometimes fall under trademark law instead)
• Facts, historical events, or data
• Methods and systems, such as a workout routine as a process, even though your written explanation of it is protected
• Works already in the public domain

What to do: Save dated copies of your drafts somewhere safe (see Step 7). That's your baseline protection.

Step 2: Check whether your country offers copyright registration

Registration rules vary a lot. Some countries have an official, optional register. Others have no government registration at all. The table gives a general overview. Confirm the current rules with the official copyright office in your country before you rely on it.

Country	Protected on creation?	Official registration?	What registration does
United States	Yes	Yes, optional (US Copyright Office)	Required before filing an infringement lawsuit for US works; can make statutory damages and legal fees available if done in time
United Kingdom	Yes	No government register	No official option; authors rely on dated records
Canada	Yes	Yes, optional (Canadian Intellectual Property Office)	Certificate serves as evidence of ownership
India	Yes	Yes, optional (Copyright Office)	Certificate serves as evidence in disputes
Australia	Yes	No government register	No official option; protection is automatic
Most EU countries	Yes	Generally no central government register	Some private deposit or timestamp services exist; check local options

Private "copyright registration" websites that aren't government bodies cannot give you more rights than you already have. At best, they give you a dated record, which you can usually create yourself for free.

What to do: Find your country in the list, or search for your national copyright office. If there's no official register, skip to Step 6.

Step 3: Decide whether to register your book

If you live in the US or publish US works, registration is optional but often worth considering. Here's why it matters under US law:

• You need it to sue. For US works, you generally must register (or have registration refused) before you can file an infringement lawsuit in federal court.
• Timing affects what you can recover. Statutory damages and attorney's fees are generally only available if you registered before the infringement started, or within three months of first publication. Without timely registration, you're usually limited to proving actual damages, which can be hard for an individual author.
• It serves as evidence. Registration made before or within five years of publication counts as prima facie evidence that your copyright is valid and that the facts in your certificate are true.

Reasons some authors skip it:

• There's a filing fee for each registration. Check the current fee schedule on the US Copyright Office website, because fees change.
• Many self-published books never face infringement, and authors weigh the cost against that risk.
• Registering later is still possible if a problem arises. The catch is that you may lose access to statutory damages for infringement that happened before registration.

What to do: If your book is a significant commercial project, or you've had content copied before, registering around publication is the safer choice.

Step 4: Register a book with the US Copyright Office

The US Copyright Office takes applications online through its Electronic Copyright Office system, known as eCO. Paper forms exist but cost more and take longer.

4.1 Create an account

Sign up for an eCO account on the US Copyright Office website. Use your legal details, because the account holder is often the person the office contacts with questions.

4.2 Choose the right application type

For a book, you'll usually register it as a "literary work." There are two common options:

• Single Application. For one work by one author, where the author is also the claimant (the owner) and the work isn't a "work made for hire." This suits many solo self-published authors and has a lower fee.
• Standard Application. For anything else, such as co-authored books, books owned by your company, or works that include material from other sources you need to exclude.

If you're unsure, the eCO system asks screening questions to steer you to the right form.

4.3 Fill in the details

You'll be asked for:

• Title of the work, plus any previous or alternative titles
• Publication status. Published or unpublished. If published, the date and country of first publication.
• Author information. Your legal name, or a pseudonym if you publish under one. You can register under a pen name and choose whether to reveal your legal name, but the record is public, so think about that.
• Claimant. Usually you, unless you've transferred rights to a company.
• Limitation of the claim. Here you exclude anything you didn't create, such as previously published text, licensed material, or AI-generated content. See Step 5.

4.4 Pay the fee

Pay online by card or a Copyright Office deposit account. Check the current amount on the fee schedule before you start.

4.5 Upload or send your deposit

The "deposit" is a copy of the work. For unpublished books, you can usually upload a digital file. For published books, the rules depend on the format, and the office may require physical copies of the best edition of a print book. The application tells you what's needed for your situation.

4.6 Wait for your certificate

Processing times vary and can stretch to several months. Your registration's effective date is the day the office received a complete application, fee and deposit, not the day the certificate arrives. Keep your confirmation email.

Sending copies to the Library of Congress

US law has a separate "mandatory deposit" rule. Generally, the owner of a work published in the US must send copies to the Copyright Office for the Library of Congress within three months of publication. Many ebook-only titles are currently exempt unless the office specifically asks for them. Sending the right copies with a registration usually satisfies this requirement. Check the Copyright Office's current guidance on mandatory deposit for your format.

This is different from a Library of Congress Control Number, which is a cataloging tool for libraries, not a copyright filing. See LCCN if you've come across both and mixed them up.

Step 5: Handle AI-assisted writing correctly

This affects many authors now, so handle it carefully.

The US Copyright Office has said that copyright protects human authorship. Material generated by an AI system is not protected on its own. Your own contributions can be protected, such as text you wrote, substantial edits, and your selection and arrangement of material.

When you register a book that contains more than a trivial amount of AI-generated material, the office asks you to:

1. Disclose that AI-generated content is included.
2. Describe the human-authored parts you are claiming.
3. Exclude the AI-generated portions in the "limitation of the claim" section.

Failing to disclose can put your registration at risk.

If you draft with an AI book tool such as Inkora, it helps to know the difference between owning a book and having copyright in it. Inkora's terms say authors own their books. Whether every sentence is protected by copyright still depends on how much human authorship is involved under your country's law. Inkora also gives you a built-in editor and chapter-level rewrite tools. If you substantially revise and add to the drafts, keep notes on what you changed, because that is the human authorship you'd describe in a registration.

Stores have their own disclosure rules, which are separate from copyright. See KDP's AI content disclosure and whether it's legal to sell AI-written books.

Step 6: Add a copyright notice to your book

A copyright notice isn't required for protection in Berne countries. In the US it hasn't been mandatory for works published since March 1, 1989. It's still worth including because it tells readers who owns the work, and in the US it can stop an infringer from claiming they didn't know the work was protected.

A standard notice has three parts:

© 2025 Jane Author

That's the symbol (or the word "Copyright"), the year of first publication, and the owner's name. Use your pen name if that's what appears on the book.

Most authors put the notice on a copyright page in the front matter, with an "all rights reserved" line, edition details, the ISBN if you have one, and any disclaimers. For wording examples and layout, see how to write a copyright page.

Inkora's export creates a print-ready interior PDF and EPUB from your manuscript. Review the copyright page text yourself before you upload, so the year, name and edition match your records.

Step 7: Keep records

Whether or not you register, records help if anyone disputes authorship.

• Keep dated draft files in a cloud folder with version history.
• Save emails with editors, beta readers and cover designers.
• Keep written agreements with anyone who contributed, such as co-authors, illustrators, ghostwriters or editors who rewrote substantial sections. Without a written assignment, a contributor may own their part.
• Keep licenses and receipts for any quoted or licensed material.
• Store your registration certificate and application receipt alongside the final files.

Mailing a copy to yourself, sometimes called "poor man's copyright," is not a substitute for registration. The US Copyright Office says so directly. Dated digital records are just as useful as evidence.

An ISBN or Amazon listing doesn't copyright your book

An ISBN is a product identifier for a specific edition. It has nothing to do with copyright ownership. The same goes for an ASIN, a Google GGKEY, or any store listing. Uploading to KDP or another store doesn't register your copyright, though the store's terms usually require you to confirm that you hold the rights to publish.

If you're sorting out identifiers at the same time, see do I need an ISBN. For store-by-store upload steps, the publishing guides cover each platform.

Common problems and fixes

You published months ago and never registered. Registration in the US is still possible. Statutory damages for infringement that already happened may be off the table, but registration still lets you sue and helps with future infringement. Register now if the book matters to you commercially.

You found your book being sold or copied without permission. Collect evidence first: screenshots, URLs, dates and seller names. Most stores and hosting services have a copyright infringement or DMCA takedown form. Your dated records and any registration certificate make these claims stronger. For anything beyond a takedown, consult a lawyer.

You made a mistake on your US registration. If the error is minor, such as a typo, you can usually file a supplementary registration to correct or amplify the record. Don't file a whole new basic registration for the same version to fix a small error.

You released a revised edition. A new edition with substantial new material can be registered separately. That registration covers only the new material, so you'd exclude the earlier, already registered text.

A co-author or editor claims part of the book. Check your written agreements. If there aren't any, get legal advice before publishing further editions. Next time, sign a short contract before work starts.

You quoted song lyrics or poetry. Short quotations can still need permission, and song lyrics in particular are often tightly controlled. Request permission from the rights holder or rewrite the passage. Fair use (US) and fair dealing (UK and others) are narrow and decided case by case.

You assumed your title was protected. Titles generally can't be copyrighted. If a title is central to a brand or series, ask a lawyer about trademark protection.

Your book is protected as soon as you write it. Registration is an optional extra layer that matters most in the US if you might ever need to enforce your rights. Add a clear copyright notice, keep good records, disclose any AI-generated material honestly, and check your national copyright office for the current fees and forms.
