Legal Deposit: Must You Send Your Self-Published Book to the British Library?

Last reviewed by Robert Prime, July 2026

Yes — if you publish a book in the UK, including self-publishing it, you are legally required to send one copy to the British Library within one month of publication. The obligation comes from the Legal Deposit Libraries Act 2003, it applies regardless of how small your print run is, and it costs you nothing but a copy of the book and the postage. Five further libraries — the Bodleian in Oxford, Cambridge University Library, the National Libraries of Scotland and Wales, and Trinity College Dublin — are entitled to request a copy each within a year of publication, usually through a single shared agency.

Most self-published authors have never heard of this. The good news: compliance is cheap, the upside is genuine (your book preserved in the national collection, catalogued for researchers, forever), and enforcement against small publishers is, in practice, a polite letter rather than a raid. Here's exactly what the law asks and how to do it in one trip to the post office.

TL;DR — Key Takeaways

• It's the law, not a courtesy. The Legal Deposit Libraries Act 2003 requires publishers — a term that includes self-publishers — to deposit one copy of every UK publication with the British Library within one month of publication.
• Five more libraries can claim a copy within one year, via the Agency for the Legal Deposit Libraries (ALDL). Many publishers simply send five copies to the Agency proactively alongside the British Library copy.
• You bear the cost — the copies and postage. There's no fee, and no payment to you either.
• Digital publications are covered too, under the 2013 Non-Print Works Regulations; ebook-only publishers can deposit digitally rather than in print.
• The upside: permanent preservation in the national collection, a British Library catalogue record (visible to librarians and researchers), and — via cataloguing — a small legitimacy signal most self-published books never bother to earn.

What does the law actually require?

The Act works in two tiers:

Tier one — the British Library. You must deposit one copy of the best edition of your publication (if you print both hardback and paperback, the hardback is the "best" edition) with the British Library's Legal Deposit Office in Boston Spa, West Yorkshire, within one month of publication. This is an automatic duty: the Library doesn't have to ask.

Tier two — the other five. The Bodleian Library (Oxford), Cambridge University Library, the National Library of Scotland, the National Library of Wales, and Trinity College Dublin are each entitled to one copy — but they have to claim it, within one year of publication, and you then have one month to comply. In practice the five claim collectively through the Agency for the Legal Deposit Libraries (ALDL) in Edinburgh, and in even more practice, many publishers skip the request-and-wait dance and post five copies to the Agency at the same time as the British Library copy. For a self-publisher that's the tidy option: six copies, two parcels, done.

Note Trinity College Dublin's presence on the list: it's a legacy of the deposit system predating Irish independence, and it means UK legal deposit reaches one library outside the UK. (Ireland has its own separate deposit law for books published there.)

Does this really apply to a print-on-demand KDP book?

If your book is published in the United Kingdom and made available to the public, yes. The Act doesn't care about print run, business size, or whether the "publisher" is a company or a person with a KDP account — the definition follows from the act of publishing, not the letterhead. A POD paperback sold to UK buyers by a UK-based self-publisher falls within the scheme, and both the British Library and the ALDL explicitly encourage self-published authors to deposit.

The honest nuances:

• Enforcement is gentle. Failure to deposit is technically enforceable (a court can order deposit), but what actually happens is the libraries write and ask. Deposit anyway — it's one of the cheapest pieces of professional behaviour available to you.
• You order the copies at print cost. For a KDP book, that's an author copy order — six copies of a typical paperback plus postage usually comes to less than a tank of petrol.
• The deposited copy earns nothing. No PLR loans (deposit libraries are reference collections, not lending libraries), no sale. The related-but-different scheme that does pay you for library lending is Public Lending Right — register for that separately.

What about ebooks and digital-only publishing?

Since the Legal Deposit Libraries (Non-Print Works) Regulations 2013, the deposit system covers digital publications — ebooks, digital-only journals, even websites (which the libraries archive by crawling, no action needed from you). Two things follow for indie authors:

1. If you publish in print and digital, depositing the print edition satisfies the duty — the print copy is the "best edition", and the libraries generally prefer it.
2. If you're ebook-only, deposit digitally. The British Library operates a publisher deposit portal for e-publications; contact its digital deposit team (or start at bl.uk's legal deposit pages) and they'll set you up. The 2013 regulations were designed around exactly this case — a growing share of UK publishing that never touches paper.

How to comply — the 30-minute version

1. Order six author copies of your finished book from KDP (print cost + delivery). If you publish hardback and paperback, the British Library copy should be the hardback.
2. Post one copy to: Legal Deposit Office, The British Library, Boston Spa, Wetherby, West Yorkshire, LS23 7BY. Include a note with the title, ISBN, publication date and your contact details.
3. Post five copies to the Agency for the Legal Deposit Libraries in Edinburgh (current address and any format preferences are on legaldeposit.org — check before sending, and note the Agency accepts proactive deposits without waiting for a claim).
4. Keep the proof of postage. That's your compliance record.
5. Do it within a month of your publication date — and for each new edition with substantive changes or a new ISBN, the duty applies afresh. A new cover alone doesn't create a new edition; a revised and re-ISBN'd second edition does.

While you're in housekeeping mode, this pairs naturally with the rest of the legal checklist — copyright and your copyright page, ISBN registration (Nielsen registration is also how UK bookshops and libraries discover your book exists), and tax registration. None of it is glamorous; all of it is what separates a book that exists officially from one that only exists on Amazon.

And since the deposited copy is the version of record that sits in the national collection permanently: make it one you're proud of. If the interior needs professionalising first, our formatting service delivers a print-ready PDF and Kindle EPUB from £69, usually within 24 hours.

Frequently Asked Questions

Do self-published authors have to send their book to the British Library?

Yes. The Legal Deposit Libraries Act 2003 requires one copy of every book published in the UK to be deposited with the British Library within one month of publication, and this applies to self-published books regardless of print run. Compliance costs only the copy and postage.

How many copies do I need to send in total?

One to the British Library (automatic duty), and up to five more if claimed within a year by the other deposit libraries — the Bodleian, Cambridge University Library, the National Libraries of Scotland and Wales, and Trinity College Dublin — via the Agency for the Legal Deposit Libraries. Many publishers send all six proactively: one parcel to Boston Spa, one to the Agency in Edinburgh.

Is there a penalty for not depositing my book?

The duty is legally enforceable — a court can order compliance — but in practice the libraries pursue missing deposits by writing to the publisher. Depositing promptly avoids the correspondence and gets your book into the national collection and catalogue.

Does legal deposit apply to ebooks?

Yes. Since the Non-Print Works Regulations 2013, digital publications fall within legal deposit. If you publish in print, the print copy satisfies the duty; if you're digital-only, the British Library accepts ebook deposit through its digital publisher deposit route.

Do I get paid when my deposited book is used?

No — legal deposit is preservation, not lending, and carries no payment. The scheme that pays UK authors for library use is Public Lending Right (PLR), which covers loans from public libraries and requires separate free registration with the British Library.
