There is a UK scheme that pays authors a small amount every time one of their books is borrowed from a public library. It's been running since 1979, it's administered by the British Library out of Boston Spa, and it's open to self-published authors in exactly the same way it's open to anyone published by Penguin or HarperCollins. It's called Public Lending Right, or PLR, and most indie authors I talk to either haven't heard of it or assume it doesn't apply to them.
It does apply. But there's a catch large enough to drive a Transit van through, and it has the word "Kindle" painted on the side. Here's how the scheme actually works, who qualifies, and what you need to do before 30 June to stop leaving free money on the table.
What PLR is
PLR is a government scheme funded out of a fixed annual pot — just over six million pounds at time of writing — that gets divided up among registered authors based on how often their books were borrowed from UK public libraries during the PLR year. The rate per loan for the 2024/25 scheme year is 12.40 pence, up from 11.76p the year before. The minimum payment is £1, and the maximum any single author can receive in a year is capped at £6,600.
The PLR year runs from 1 July to 30 June. Loans racked up during that window are counted, the maths is done over the autumn, and payments drop into your bank account the following February. So the loans being sampled right now, as I'm writing this, are the ones that'll pay out in February 2027.
The loans aren't counted at every library — that would be an administrative nightmare — but at a rotating sample of around thirty library authorities each year. Your loan data is then scaled up to estimate your true national total. It's not perfect, but it's how every country running a PLR scheme does it, and the sampling method has been refined over forty-odd years.
Who's eligible
To register for UK PLR you need to be either named on the title page of the book, or entitled to a royalty payment from the publisher. For a self-published author, that's you on both counts, which is convenient. You also need to have your only or principal home in the UK or the European Economic Area (or Switzerland). If you've emigrated to Los Angeles to pursue your screenwriting dreams, you can't claim UK PLR on books you write from there.
Illustrators, translators, editors who are named on the title page, and even audiobook narrators can all register under their own share of the royalty. For most indie novelists that's academic — you're the only contributor — but worth knowing if you've commissioned a cover artist whose name goes on the title page, or you've narrated your own audiobook.
The Kindle-shaped catch
Here is the bit that trips up indie authors, and it's fundamental. PLR only pays on books with a valid ISBN that are actually available to be lent by UK public libraries. The word "lent" is doing a lot of work in that sentence.
A Kindle ebook sold through KDP is not in that system. Kindle editions use Amazon's ASIN identifier rather than a real ISBN, and Amazon has never licensed its Kindle content to the UK public library lending platforms — OverDrive, Libby, BorrowBox, the lot. Your KDP-only ebook, no matter how many people "borrow" it through Kindle Unlimited, will earn you precisely nothing in PLR terms. KU is not a library. It's a rental club run by Amazon.
The same problem applies to Audible download editions and KDP-only audiobook editions, for the same reason. Amazon's digital catalogue sits outside the UK library ecosystem entirely.
So the first question a self-published author needs to ask, before they even look at the PLR registration form, is: is any edition of my book actually in a shape that UK libraries can lend?
Getting your book into a lendable state
There are two realistic routes for an indie, and most authors end up doing both.
The first is print. A paperback with its own ISBN, available through a catalogue libraries actually use, can be ordered and stocked by any UK library authority that fancies it. In practice, that means distributing your paperback through IngramSpark (or via Draft2Digital's print partnership with Ingram), which puts your book into the wholesale catalogue that UK library suppliers like Askews & Holts draw from. A KDP-only paperback is print-on-demand on Amazon's infrastructure, and while it can in theory be ordered through a library supplier, it rarely is. IngramSpark distribution is the route most library-minded indies take.
The second is ebook. If you want your ebook in the UK library lending system, you need to distribute it through an aggregator that feeds the library platforms — Draft2Digital and PublishDrive both push to OverDrive and other library-facing services, though typically as part of a wide-distribution package rather than an exclusive one. You'll need your own ISBN (not the free KDP one, which is tied to Amazon) and you'll need to be out of KDP Select, since Select requires ebook exclusivity.
None of this is free, and it's a deliberate trade-off. Going wide with an ISBN and an aggregator costs money and can reduce Amazon visibility. For some indies, particularly those deep in KU, the PLR upside isn't worth the ecosystem move. For others — especially those already publishing wide — it's a few quid of admin for a small but genuine recurring cheque.
How to register
Once you have a lendable edition with a real ISBN, registration itself is straightforward. The official site is bl.uk/plr, run by the British Library. You create an account, verify your identity, and register each eligible book by its ISBN. Each format — paperback, hardback, ebook, audiobook — is registered as a separate "book share" because they each have their own ISBN and their own loan pattern.
The deadline to be counted in the current PLR year is 30 June. Register a book after that, and its loans only start being counted from the following PLR year onwards. So if you publish a new edition in, say, September, you want its ISBN registered well before the following June, not left in the drawer.
One related requirement worth flagging while we're here: UK legal deposit. By law, one copy of every book published in the UK must be sent to the British Library, and publishers can also request copies on behalf of five other legal deposit libraries (Oxford, Cambridge, Trinity College Dublin, the National Libraries of Scotland and Wales). Self-publishers are covered by this too — you're the publisher. It's a separate process from PLR, but if you're corresponding with the British Library about PLR already, it's a good prompt to make sure your legal deposit obligation isn't being quietly ignored.
Is it worth the effort
For most indies the honest answer is: not huge, but not nothing. A paperback that gets a hundred UK library loans a year earns you about twelve quid. A backlist of ten titles each doing the same puts you over a hundred pounds — enough to pay for a year's worth of author-copy postage, or a chunk of next year's cover design.
What makes it worth doing is that the work is almost entirely front-loaded. Register once, keep your contact details current, add any new editions as they come out, and the British Library sorts the rest. It's the rarest kind of author income: passive, legitimate, and entirely outside Amazon's reach.
Your book launch still needs planning, pricing, metadata, covers, and the hundred other decisions that turn "I've written a book" into "people are actually buying it." That's what the WIPsage book launch tool was built for — a structured plan for the things that make or break your first few weeks. PLR is gravy. Make sure the roast is on first.
