The Kindle Owners’ Lending Library is coming to the UK, France and Germany later this month. The Lending Library will be available to Kindle owners who have bought an Amazon Prime membership.
Terms Of Kindle Owners’ Lending Library
1. Kindle owners refers to those owning a Kindle device (all Kindle generations including the new Paperwhite announced yesterday) – not those with the Kindle reader app on a non-Amazon tablet or phone/PC.
2. Amazon Prime is an existing service which offers unlimited free one day delivery on millions of eligible items for an annual cost of £49.
Users who satisfy both conditions will be able to borrow popular Kindle books at no extra cost, as frequently as one book per month and with no due dates. The borrowed book can be read on multiple Kindle devices, as long as they are registered to the same eligible account, but cannot be read on Kindle reading apps.
The Kindle Owners’ Lending Library range will consist of more than 200,000 titles, including all seven Harry Potter books and other top sellers in the Amazon Kindle Store.
Further details are available from Amazon UK here.

Conclusion
If you already have an Amazon Prime account, the Lending Library should be a good deal as you can borrow up to 12 books a year for free.
Whether it is worth paying £49 to buy a new Prime account to gain access to the Library is more subjective. It may depend on how much you value the one day delivery service and/or whether you would normally buy up to 12 books from those in the Library selection anyway.
