ISBNs, Barcodes & Copyright {Who Handles What When You Publish}

If you’re weighing whether to self-publish or partner with a publisher, it’s easy to focus on the big, visible pieces like editing, the cover, the launch. But a few behind-the-scenes details shape who controls your book for years to come. ISBNs, barcodes, Library of Congress records and copyright registration all fall into that category.

The paperwork is the same either way. What changes is who handles it and whose name ends up on it. Here’s how it works on each publishing path.

What Each Piece Does

ISBN

An ISBN (International Standard Book Number) is a 13-digit number that identifies one specific edition of a book. Each format needs its own: paperback, hardcover, ebook and audiobook. Whoever buys the ISBN is listed as the publisher of record.

Barcode

The barcode on the back of a print book is the ISBN in scannable form. It’s built from the ISBN and placed on the back cover design.

LCCN

A Library of Congress Control Number (LCCN) helps libraries catalog your book. It’s requested before publication and printed on the copyright page.

Copyright Registration

Your words are protected by copyright the moment they’re written down. Registration with the U.S. Copyright Office is a separate, formal step that creates a public record of ownership. It’s what gives you real options if your work is ever copied.

If You Self-Publish on Your Own

Fully independent authors handle every one of these steps themselves. That’s very doable, and it’s worth knowing the list before you start:

• Buy your ISBNs from Bowker, the official U.S. agency, one per format. Platforms like KDP offer a free ISBN, but the platform is then listed as the publisher, and that number only works on that platform.
• Request your LCCN through the Library of Congress before your release date.
• Get your barcode generated through KDP or IngramSpark, or have your cover designer place it.
• Write your copyright page, including the copyright notice, ISBNs for each format and any required permissions or Bible version citations.
• File your copyright registration with the U.S. Copyright Office after the book is live.

Each step is manageable on its own. Together, they’re a checklist that’s easy to lose track of in the final weeks before launch.

If You Partner with a Publisher

When you publish with a partner publisher, those steps move to the publisher’s side of the table. Here’s how we handle them at Market Refined Publishing:

• ISBNs: We purchase the ISBNs under our MRP imprint for every format of your book.
• Library of Congress: We register the book with the Library of Congress during the publishing phase.
• Barcodes: Our designers place the barcode as part of the full cover design, or we ensure each platform properly generates and places the barcode as part of the publishing process.
• Copyright page: We place our own copyright page in all books we publish, which includes our use limitations for the published work, your ISBNs, publishing details and any Bible versions or citations your book needs.
• Copyright registration: After your book is live, we file the federal copyright registration on your behalf, listing both you and MRP. The filing is part of our imprint services, and we share the registration certificate with you once it’s issued.

You still own your manuscript and its message. The difference is that the paperwork is handled by a team that does it for every book, every time.

Why Copyright Registration Matters Now

Registration used to feel optional for many authors. Recent cases have changed that. In the class-action settlement over AI training on pirated books, authors were eligible for compensation only if their books had been formally registered with the U.S. Copyright Office. Many authors learned their books had never been registered.

Timing matters too. In the U.S., you generally need a registration before you can file an infringement lawsuit. Registering within three months of publication also makes you eligible for statutory damages and attorney’s fees.

That’s why MRP made federal copyright registration a standard step for every new release. It’s one practical way we steward our authors’ work well.

Questions to Ask Any Publishing Partner

Before you sign with any publisher, including us, ask:

• Whose name is listed as the publisher on my ISBNs?
• Will my book be registered with the Library of Congress?
• Who files the copyright registration, and when?
• Who is listed on the registration, and will I receive a copy of the certificate?
• What happens to my ISBNs and files if I ever move my book elsewhere?

Clear answers are a good sign. Vague ones are worth a follow-up conversation.

Our rule of thumb? Know who handles these details before you choose your path, not after your book is live.

One Thing to Do Next

Make a two-column list: “I’ll handle it” and “My publisher handles it.” Sort each item above into a column. If most of the list lands on your side and that feels like a lot, a partner publisher may be the better fit. If you’d like to compare notes, our publishing services and frequently asked questions for publishing are good places to start.
