Copyright: what you have automatically, and what registering adds

Copyright is the corner of publishing where confident wrong advice circulates fastest, usually as a warning that you must register your book before you publish it. In most countries that is not how it works.

Two things are true at once: you own your book without doing anything, and registering it, where registration exists, can still be worth doing.

Your copyright starts when the words are fixed

In most countries, copyright exists the moment a work is fixed in a tangible form — typed into a file, written in a notebook, recorded. There is no form to file and no office that has to agree with you first. The draft on your laptop is already covered.

The principle sits in international treaty, which is why it holds so widely. The details do not: how long protection lasts and which exceptions apply are national law.

Mailing yourself a copy of the manuscript proves a postmark at best, and carries no weight in most systems.

The notice is a statement, not a grant

Print it anyway. It tells a librarian, a retailer and a rights buyer who owns the book and from what year, and in some countries it bears on whether an infringer can claim they did not know. What it never does is confer the right. What belongs on a copyright page covers the rest of that page.

What registration adds

Many countries operate a copyright register. Where one exists, this is roughly what it gives you:

A public record. A dated official entry naming this work, this author, this version. Pointing at a register entry is easier than reconstructing a chain of drafts years later.
Procedural advantages if you ever enforce. In some countries registration is a precondition of bringing certain claims, or unlocks remedies otherwise unavailable, or changes what you have to prove. In others it does none of that.
A cleaner rights story. Anyone buying rights from you — a translation publisher, an audiobook producer — is buying something they would like verified.

None of it is protection you lacked. It is proof and process wrapped around protection you already had.

It is a country-by-country system

There is no world copyright registry. Each country that runs one runs its own, with its own office, its own rules about who may register and what a registration covers, its own fees and its own processing times. Some have no register at all.

Registering in one country does not register you in another; international protection comes from treaties obliging countries to recognize each other's authors, not from a global filing. Check what applies where you live and where you publish, with the body that runs the system rather than in an article.

Legal deposit is a different thing again

Many countries require published books to be supplied to a national library. It surprises self-publishers, because it is often the only genuinely mandatory step in the process.

Copyright is ownership. Automatic in most countries.
Registration is a record of that ownership. Optional where it is offered at all.
Legal deposit is a supply obligation to a library. Mandatory where it applies, and unrelated to whether you registered.

None of the three is an ISBN. An ISBN is a product code identifying one edition in one binding; it registers nothing and proves nothing about ownership — see Do you need your own ISBN?. Find out what your country expects before you publish.

In the Interior Formatter. The copyright page is built from fields — rights holder, year, edition, ISBN — so the version you register and the version you print describe the same book, and a revised edition carries its own line instead of inheriting the first edition's.

Register the version you published, and only the new part of the next one

Register the text you released, not the draft you had when you started the paperwork — wait for the final file, after proofing and the last typo pass.

A registration covers the work as deposited, so substantial new material in a later edition is usually handled as its own filing covering what is new. Fixing typos is not a new edition and needs nothing; three added chapters or a rewritten ending is a different book to a librarian and often to a register. Rules differ by country — ask the office running the one you are using.

Joint authorship

Two authors writing one book normally own it jointly, and the default rules for what either may do alone — license a translation, grant an audio deal, withdraw the book — vary considerably. In some countries one co-owner can grant a non-exclusive license without the other; in others nobody can act alone.

Write down who owns what and who decides what before the book exists, while everyone is still friendly.

Work you commissioned

Cover art, illustrations, maps, a translation: the person who made it owns the copyright in it unless your agreement says otherwise. Paying an invoice does not transfer copyright by default in most countries.

What you have is what the agreement gives you — an assignment, so you own it, or a license, so you may use it in named ways, often limited to one edition, format, territory or term. Read yours before you put the art on merchandise, a second edition or a foreign-language cover. Hire a cover designer, or do it yourself? covers what to settle up front.

Where general information stops

All of this is how book publishing usually works, it varies by country, and none of it is legal advice about your book.

Anything contested is worth an hour of a lawyer's time: a co-author who disagrees, an estate, a publisher you once signed with, a designer whose agreement you cannot find, or somebody selling your book without permission. An hour under the law that actually applies is cheap next to being wrong in public.

Make yours

Everything here is built into the tools, and they are free to use: name your book, bring your manuscript or your artwork, and work as long as you like. You only pay when you want the files without the preview watermark.
