Amazon book publishers, primarily through Kindle Direct Publishing (KDP), provide a user-friendly platform for authors to self-publish their work. KDP enables writers to publish eBooks and paperbacks, offering global distribution, flexible royalty options, and complete creative control. Authors can design their own covers, set pricing, and update their books at any time. Amazon’s vast marketplace ensures visibility to millions of potential readers, while Print-on-Demand technology eliminates the need for upfront printing costs.
