Kindle Direct Publishing (KDP) is Amazon.com's digital book publishing service, introduced in November 2007 alongside the debut of the original Amazon Kindle device. Originally named Digital Text Platform, it allows writers and publishers to distribute their titles through the Amazon Kindle Store.
Through the KDP portal, authors can upload manuscripts in various file types and set prices ranging from $0.99 up to $200.00. The platform accommodates content in 44 different languages.
In 2016, Amazon enhanced KDP by adding a print-on-demand feature for paperback editions, which was followed by the introduction of a hardback (case laminated) printing option in 2021.
History
KDP began its public beta testing phase in late 2007. In a 2009 interview, Amazon's CEO Jeff Bezos revealed that Amazon retains 65% of revenue from Kindle e-book sales, with the remaining 35% split between authors and publishers. By 2010, to rival Apple's offerings, Amazon introduced a 70% royalty tier available under certain conditions.
By 2016, Amazon had published four million e-books, with self-published titles via KDP accounting for 40%, underscoring KDP’s dominant presence in the digital publishing market.
In April 2017, Amazon launched Kindle Create, a tool designed to simplify converting Word and PDF documents into Kindle-ready formats, consolidating previous conversion utilities into one streamlined application.
Royalty payments through KDP exceeded $260 million in 2018 and went beyond $300 million in 2019, demonstrating robust growth and profitability within Amazon’s publishing services.
Kindle Scout (discontinued)
Introduced in 2014, Kindle Scout was a platform where unpublished authors could submit novels for reader nomination. Users could explore various genres and read up to the first 5,000 words before nominating as many as three books for Kindle Press publication. Selected writers received an advance along with professional editing support. The program stopped accepting new submissions in April 2018 and concluded after releasing 293 titles.
Kindle Worlds (discontinued)
Launched in May 2013, Kindle Worlds provided an official marketplace for fan fiction based on licensed entertainment franchises. Amazon terminated this service in August 2018.
Kindle Publishing for Blogs (discontinued)/Periodicals
Beginning in early 2008, Amazon permitted blogs such as Ars Technica and TechCrunch to publish content on the Kindle platform; by May 2009 this was extended to all blogs. Subscription pricing was controlled by Amazon, which retained 70% of revenue generated. Due to minimal adoption, this blog service ended on August 19, 2019, transitioning focus toward Kindle Publishing for Periodicals aimed at newspapers and magazines.
KDP Select
Enrollment in the KDP Select program requires exclusivity to Amazon for eBook distribution, barring minor exceptions. Authors can opt out after a ninety-day period; otherwise, enrollment automatically renews. Titles enrolled in KDP Select become part of Kindle Unlimited, a subscription service offering unlimited access to eBooks.
Initially, Amazon compensated authors with a fixed payment if readers completed at least 10% of their book—a model that disadvantaged longer works. In July 2015, this shifted to a per-page-read payment system. Authors receive a portion of a monthly fund—starting at $1.2 million in April 2014 and increasing to $11 million by July 2015, reaching $28.5 million in 2019—equating approximately to half a cent for every page read.
Kindle Vella
Introduced in 2021 as a platform for serialized fiction, Kindle Vella aimed to rival services like Wattpad and Radish but was ultimately discontinued in February 2025. While technology outlets such as GeekWire commended it for bringing a modern storytelling approach tailored to younger demographics, the platform failed to achieve widespread adoption. According to Publishers Weekly, its format of brief, smartphone-optimized story segments resonated primarily with younger audiences.
Conversely, Android Central criticized Kindle Vella’s token-based payment system and Amazon’s corporate image, which reportedly hindered its attractiveness to authors. Nevertheless, the platform fit within Amazon’s broader strategy to enhance reader interaction and generate revenue from serialized narratives amid intensifying competition from platforms including Wattpad, Webtoon, Patreon, and others emphasizing creator-driven monetization.
Hardcover publication
Kindle Direct Publishing (KDP) offers more than just e-books and paperbacks by providing authors with the option to publish hardcover editions. This feature caters to readers who favor traditional hardbound books and can elevate the perceived prestige and value of an author’s work.
Data sharing and retention
KDP has faced scrutiny regarding its revenue-sharing policies and the mandatory lendability feature, which has been exploited by third-party services such as Lendink. Critics have also questioned Amazon’s e-book business model, particularly its licensing framework that limits user ownership compared to physical copies. Due to Amazon’s digital rights management (DRM), e-books are licensed rather than sold, restricting resale rights—a legal issue that remains unsettled worldwide.
Furthermore, authors are unable to completely remove unpublished or retired titles from KDP’s servers. Although these books can be unpublished and taken off the market, their digital files remain stored indefinitely, even if they contain errors or are outdated. This policy also applies to paperbacks assigned ISBNs. Authors must accept Terms & Conditions that mandate indefinite retention of files without public disclosure or explanation. There are no exceptions for minors or vulnerable users who consent to these terms. Even when accounts are deleted, uploaded content persists on Amazon’s servers. In instances of plagiarism, authors must work with Amazon’s Legal Department to pursue copyright infringement claims.
Hate speech and misinformation
Kindle Direct Publishing has been criticized for allowing offensive and potentially unlawful content, including hate speech, neo-Nazi propaganda, misinformation about autism, and illegal sexual material. Users on platforms like Reddit and 4Chan have described KDP’s quality control as minimal, permitting nearly any content to be published with limited legal oversight. Some contentious works have been removed following legal challenges—for example, The Pedophile's Guide to Love and Pleasure by Phillip R. Greaves—as well as titles promoting extremist views or false information.
Testing Amazon’s content moderation, Wired journalist Matthew Reynolds uploaded a fabricated Kindle eBook titled How To Cure Autism: A guide to using chlorine dioxide to cure autism, which was approved within two hours. Amazon’s system even suggested a stock cover implying FDA endorsement. Numerous genuine Kindle publications advocating bleach treatments and other pseudoscientific remedies continue to be available on the platform.
Pirated books and plagiarism
The issue of plagiarism has increasingly impacted Kindle Direct Publishing, affecting notable authors such as Nora Roberts and Stephen King. Illegitimately copied titles frequently maintain their metadata on platforms like Google Books, Goodreads, and Ingram when assigned an ISBN (which KDP provides at no cost). However, many pirated eBooks rely solely on ASINs to avoid detection, complicating efforts to pursue legal action since perpetrators often use false identities. Additionally, plagiarized metadata can override authentic author information on sites like Goodreads and Google Books, damaging the original authors' reputations.
Author David Gaughran has voiced concerns regarding Amazon’s inadequate measures against fraud, highlighting that top offenders may generate earnings exceeding $100,000 monthly by exploiting the system and funneling profits into advertising that ultimately benefits Amazon. Nora Roberts criticized Kindle Direct Publishing’s framework as "absurdly weak" and exasperating due to its prioritization of quantity rather than quality.
Amazon defends its limited quality oversight by pointing to routine plagiarism screenings against existing works. The Urban Writers group supports Amazon’s position, emphasizing that accounts identified for plagiarism are deactivated. Nevertheless, Plagiarism Today cites incidents such as the Cristiane Serruya case to advocate for more stringent copyright enforcement. Typically, Amazon removes infringing content only after receiving complaints, protected legally under the Digital Millennium Copyright Act (DMCA) and Section 230 of the Communications Decency Act, which exempt it from pre-publication content verification.
Although plagiarism is not exclusive to Amazon subsidiaries like Kindle Direct Publishing and Goodreads, their methods have hindered authors’ abilities to safeguard their identities and reputations online due to the impact of plagiarized metadata on book listings and discoverability.
Lyndon McLeod
In December 2021, Lyndon McLeod (also known as Roman McClay) carried out a mass shooting in Denver and Lakewood, Colorado, resulting in five fatalities. McLeod had self-published a novel series titled Sanction via Amazon's Kindle Direct Publishing, which contained detailed plans of his attack along with the names of some victims.
