For years, the trade-off with Kindle Unlimited was easy to explain. Enroll in KDP Select, earn KU page reads, and give up every other channel for 90 days. Libraries were part of what you gave up. That is no longer true, and much of the KU-versus-wide advice still in circulation has not caught up.
In 2025, Amazon changed the KDP Select exclusivity terms to allow public library distribution as an exception. If you enrolled in KU believing it locked you out of libraries entirely, this one is worth a few minutes.
What actually changed in KDP Select?
Amazon updated the KDP Select enrollment terms so public libraries are an explicit exception to exclusivity. The revised wording reads: “During the 90-day enrollment period, the Kindle eBook can only be distributed through KDP and public libraries.” In plain terms, an enrolled KU book can be lent through library platforms while it stays in Kindle Unlimited and keeps earning page reads.
Which library platforms can KU books reach?
A KU-enrolled ebook can reach the major library lending platforms through a distributor, including OverDrive (Libby), hoopla, cloudLibrary, BorrowBox, and Vivlio. You do not sign up for each one separately. You go through an aggregator such as Draft2Digital, which handles the library channel while your book stays enrolled in KU.
What is still off-limits while you are in KU?
Retail is still exclusive. Selling the same ebook on Apple Books, Barnes & Noble, or Kobo during the enrollment period still breaks the KDP Select term and can cost you your KU eligibility. The exception is libraries only, not other stores.
Does this change the KU versus wide decision?
It removes one argument from the go-wide column. Losing the library market used to be a genuine cost of choosing KU, and for authors whose readers borrow heavily, that cost sometimes tipped the decision. With libraries open on both sides now, they drop out of the comparison. The call comes back to what actually moves revenue: your release cadence, where your readers buy, and the traffic you can run. I walk through that in KU or wide: what the decision actually depends on.
Should you add library distribution to your KU book?
For most authors, it is worth claiming. Library borrows reach readers who were never going to buy the ebook outright, and library lending has been a growing share of author income. It does not eat into your KU page reads, because it is a separate audience through a separate channel. The things to weigh are the distributor’s cut and any fee to reach the library platforms.

Frequently asked questions
Can Kindle Unlimited books be in libraries?
Yes, since Amazon’s 2025 update to KDP Select. An enrolled KU ebook can be distributed to public library platforms like OverDrive and hoopla through a distributor while staying in Kindle Unlimited and continuing to earn page reads.
Does putting a KU book in libraries break exclusivity?
No. Public libraries are now an explicit exception to KDP Select exclusivity. What still breaks it is retail distribution to other stores such as Apple Books, Barnes & Noble, or Kobo during the 90-day enrollment period.
How do you get a KU book into libraries?
Through a distributor that offers library distribution, such as Draft2Digital, rather than approaching each platform yourself. The distributor pushes your title to services like OverDrive, hoopla, and cloudLibrary while it stays enrolled in KU.
Do library borrows affect KU page reads?
No. Library lending is a separate channel with a separate audience, so it does not reduce your Kindle Unlimited page reads. It adds a revenue stream rather than shifting one.
