Professional ISBN & Copyright Registration Services

Yes. Industry convention requires a unique ISBN for each distinct format — eBook, paperback, and hardcover are each treated as separate products by retail and library systems, even though the content is identical. If you later produce an audiobook, that needs its own ISBN as well. We register every format your book needs so nothing gets left out and your catalog listings stay accurate across every retailer.

Thorpe-Bowker is the exclusive official ISBN registration agency for Australia — there is no alternative or competing agency, and individual authors cannot self-register an ISBN outside this system. This is standard practice internationally; most countries designate a single national ISBN agency. We handle the registration process through Thorpe-Bowker on your behalf, always listing you as the publisher of record.

The publisher of record is whoever is officially listed as controlling a specific ISBN in Thorpe-Bowker's system. If your publishing service registers the ISBN under their own company name rather than yours, they retain administrative control over your book's official listing — which can make switching services, republishing independently, or making basic updates unexpectedly difficult later. We always register you as the publisher of record, meaning you retain that control permanently, regardless of your future relationship with us.

Generally, yes, in principle. Australia is a signatory to major international copyright treaties (including the Berne Convention), meaning your automatic Australian copyright is recognised in most member countries without any additional registration. That said, enforcing your rights practically — actually pursuing legal action against infringement in another country — is a separate and more complex matter that depends on that country's specific laws and enforcement mechanisms. For US-specific enforcement concerns, US Copyright Office registration is worth discussing, since it is a prerequisite for filing an infringement lawsuit there.

ISBN allocation through Thorpe-Bowker is typically fast — usually a matter of days once your book's details are finalised, rather than weeks. Since Australian copyright requires no registration process at all, there is no separate copyright timeline to factor in domestically. If you are pursuing optional US Copyright Office registration alongside your Australian ISBN setup, that process generally takes longer and follows a different timeline, which we outline clearly if it applies to your project.
