How to Copyright a Book Before You Publish or Share It
You do not need to file anything to copyright a book: copyright belongs to you automatically from the moment the text is written down, in a document, a notebook or a draft in the cloud. An ISBN, a © line or a copy sent to the national library do not create it either. What writers actually lack is evidence: something that shows, to a publisher, a platform or a court, that this exact text existed on a given date and came from you. The practical steps: keep your drafts, put a trusted date on a PDF of each version before anyone else reads it, and, only if the US is a realistic place for a dispute, register with the U.S. Copyright Office.
This is general information, not legal advice for a specific dispute.
What people mean by "copyrighting a book"
Under the Berne Convention, copyright arises without formalities in almost every country. So "how do I copyright my book" usually hides a different question:
- "How do I stop someone stealing it before it's published?" – an evidence question: you need a dated record of the text.
- "What do I need to self-publish?" – an ISBN and, in most countries, legal deposit. Neither is about copyright.
- "Can I sue in the US?" – for US works, registration with the U.S. Copyright Office is required before a federal lawsuit.
The risky moments for a manuscript are when it leaves your hands: beta readers, writing groups, agents, contests, editors, posting chapters on Wattpad, Royal Road or a blog, and the period after you publish on Amazon KDP when copies are easy to scrape.
Your options, compared
| Option | What it gives you | Limit |
|---|---|---|
| ISBN | An identifier for one edition, for shops and libraries | Says nothing about who wrote the text or when |
| Legal deposit with the national library | A public archive copy after publication | Only for published works; it is an archiving duty, not a copyright filing |
| © line on the copyright page | Tells readers who claims the rights | Optional; it is a statement, not evidence |
| U.S. Copyright Office | A public record; for US works, needed before suing in a US federal court | Paid per application; requires a copy of the work; matters mainly for the US |
| Emailing the manuscript to yourself | A date you can point to | You control the account, so the date is easy to dispute |
| Qualified timestamp on a PDF of each version | This exact text existed at this moment, unchanged since, presumed accurate across the EU; nothing is published | Records your declaration, not who wrote it; keep the drafts for that |
Before anyone else reads it: a checklist
- Export a PDF of the exact version you share. DOCX, Scrivener and Google Docs files change their fingerprint on every save. A PDF you never edit stays byte-for-byte the same.
- Timestamp that PDF before it goes out. To beta readers, an agent, a contest, an editor, or before posting the first chapters online.
- Timestamp the extras too. Synopsis, outline, world-building notes, series bible and cover art, as files or in one manifest.
- Keep every draft. Old versions, notes and revision history show you writing the book. That is your answer to "you copied it".
- Log where each version went. Date, recipient, version, and the email or upload confirmation.
- Repeat for each major revision. A dated chain of drafts is far harder to argue with than one date.
- When you publish, get an ISBN and make the legal deposit your country requires. Register in the US if you sell mainly there.
What a StampR certificate adds
A StampR certificate binds the SHA-256 fingerprint of your manuscript PDF to a qualified electronic timestamp from BORICA B-Trust, together with your declaration that you are its author. Under Article 41(2) of the EU eIDAS Regulation, its date and integrity are presumed accurate in every EU member state. Your text never leaves your computer: only the fingerprint is sent, so the book stays unpublished and confidential. If a scraped copy or a suspiciously similar book appears, you or your lawyer can show on the verification page that your PDF matches the certificate and when it was timestamped.
Timestamp your manuscript before you share it – the first certificate on an account is €4.90.
What it does not replace
- It does not cover a premise, plot idea, title or genre trope. Copyright protects your text, not the idea behind it.
- It does not create or record any rights. They already exist; the certificate dates a specific file.
- It is not an ISBN or a legal deposit. You still need those to publish.
- It does not replace US registration if a US lawsuit is realistic.
- It does not replace a contract with a co-author, ghostwriter, translator or illustrator.
The wider context: copyright protection – how the right arises, and where it is weak in practice.

Frequently asked questions
Do I need to register my book to own the copyright?
No. You own the copyright from the moment you write the text, with no registration, in every Berne Convention country. Registration and timestamps are about evidence and enforcement, not ownership.
Does an ISBN copyright my book?
No. An ISBN identifies one edition for shops and libraries. It records neither the author's rights nor the date the text was written.
Can a publisher or agent steal my manuscript?
It is rare with established agents and publishers. The more common risks are scraped online chapters, contests, writing groups and former co-writers. A dated record of each version you shared covers all of them.
Is the "poor man's copyright" of mailing the manuscript to myself enough?
It is weak, because you control the envelope or mailbox. A qualified timestamp comes from an independent, supervised provider and its date is presumed accurate in EU courts.
How much does it cost to copyright a book?
Owning the copyright costs nothing. A U.S. Copyright Office application has its own fee; check copyright.gov. A StampR certificate is €4.90 for the first one on an account and €6.80 after that.
Is my manuscript uploaded?
No. The fingerprint is calculated in your browser and only the fingerprint is sent, unless you choose to store a copy.
