Lending Library The Lending Library was added in late 2011 for
Amazon Prime members with Kindle e-readers. This perk allows access to the "Kindle Owners' Lending Library" where users can borrow one e-book, choosing from over 600,000 titles as of July 2014, per calendar month from the Kindle Store for free. The library was later expanded to include
Fire tablets; as of February 2018, the service had over 1.7 million titles available.
Kindle Unlimited In July 2014, Amazon added the
Kindle Unlimited subscription service that initially offered unlimited access to over 638,000 titles and over 7,000
audiobooks for a $9.99 monthly fee. As of June 2015, there were over one million titles available in Kindle Unlimited, from publishers such as
Houghton Mifflin Harcourt,
Lonely Planet,
Simon & Schuster,
Wizarding World Digital, and
Workman Publishing Company. As of February 2017, the U.S. version of Kindle Unlimited includes over 1.5 million titles includes over 290,000 foreign language titles. Amazon pays authors by using a per-page rate and during 2016 nearly $200 million was paid to authors. In 2019, Amazon paid over $300 million to authors and publishers that provide content to Kindle Unlimited. Jeff Duntemann reported that 40% of the revenue in 2015 for his
The Cunning Blood came from the program. Because of the novel's long length he was paid more if a reader finished the book through Kindle Unlimited than from selling a copy for $2.99, Duntemann said.
Prime Reading In October 2016, another perk was added for Amazon Prime members called "Prime Reading". Prime Reading gives the ability to read as much material as they wish from a selection of over 1,000 e-books, magazines, comic books, children's books, and more for no additional fee. ==E-book pricing==
