ISBN Guide for Independent Authors
What an ISBN is, how to get one in the UK, and whether you actually need one.
What is an ISBN and Do I Need One for My Book?
ISBNA 13-digit code that uniquely identifies a book edition or format — International Standard Book Number — is a 13-digit code that uniquely identifies your book. Every edition and format of a book requires its own ISBN. A paperback and a hardback of the same title are different products and need different ISBNs.
No. If you're publishing your book on Tales From A Harrogate Caravan, you do not need an ISBN.
An ISBN is only required if you want your book stocked in bookshops, listed by wholesalers, supplied to libraries, or distributed through retailers. Since we publish and share your work directly with readers — not through the traditional bookshop/wholesaler trade — none of that applies here. You can publish through us with zero ISBN cost and zero extra paperwork.
An ISBN only becomes relevant if, separately, you also want to:
- Get your book stocked in physical bookshops
- Have it listed with wholesalers or library suppliers
- Distribute it through retailers like Amazon, Waterstones, etc.
If you do go down that route later, know that each edition/format needs its own ISBN — paperback, hardback, EPUB, and audiobook are each separately numbered, and you'd buy them from Nielsen (the UK's sole ISBN issuer).
What It Does
An ISBN identifies your book to booksellers, libraries, and distributors worldwide. It tells them who published it, what format it is, and how to order it. Without one, your book cannot be stocked in most bookshops or listed in library catalogues.
What It Does Not Do
An ISBN does not protect your copyright. It does not register your book with any legal body. It is simply an identifier — like a barcode for your book. Copyright exists automatically the moment you write something original.
Who Needs One
If you are selling through bookshops, listing on library systems, or distributing through wholesalers, you need an ISBN. If you are selling directly to readers yourself — at events, through your own website, or through us here at Tales From A Harrogate Caravan — you do not strictly need one.
How to Get an ISBN in the UK
In the UK, ISBNs are issued exclusively by Nielsen Book Services. You cannot buy them anywhere else in the UK — any other source is reselling at a markup.
Nielsen UK
Go to nielsenisbnstore.com to purchase ISBNs directly. A single ISBN costs around £89. A block of 10 costs around £164 and is far better value if you plan to publish more than one book or edition.
Single vs Block
A single ISBN makes sense if you are testing the water with one book in one format. A block of 10 is the sensible choice for anyone serious about publishing — it works out at around £16 per ISBN versus £89 for a single.
You Are the Publisher
When you buy your own ISBN, your name or imprintThe publisher name under which a book is registered — can be your own name or a chosen business name name is registered as the publisher. This matters. If you use a free ISBN from Amazon KDP or IngramSpark, they are listed as the publisher — not you.
Free ISBNs — The Catch
Amazon KDP and some other platforms offer free ISBNs. There is a catch worth understanding before you accept one.
Platform Lock-In
A free KDP ISBN can only be used for books distributed through Amazon. You cannot take that ISBN and use it elsewhere. If you later want to sell through other retailers, you need a new ISBN.
Publisher of RecordThe name officially listed as the book's publisher in ISBN and library databases
With a free platform ISBN, the platform is listed as your publisher in book databases. For most independent authors this is a cosmetic issue, but for those building a personal imprint it undermines the independence you are trying to establish.
Our Recommendation
If your plans stay with Tales From A Harrogate Caravan, none of this is a concern — you can publish with us with no ISBN at all. If you later want a wider retail presence, buy your own ISBN from Nielsen rather than relying on a free platform one. The one-off cost is worth the freedom and professionalism it gives you.
Legal Deposit — A Separate Requirement
Legal deposit is a different requirement from an ISBN, and it applies whether or not your book has one.
What It Is
Under UK law, publishing a book — including a self-published print copy — means sending one copy to the British Library within one month of publication. This applies to Tales From A Harrogate Caravan authors too.
It Is Free
There is no fee. You are not buying anything or paying to be listed — you simply send one copy and the British Library covers everything on their end. The only cost is a single printed copy and postage.
