Amazon's Kindle Direct Publishing (KDP) is a platform that allows authors and publishers to self-publish their books in digital and print formats. It provides an easy way for writers to reach a global audience by making their works available on the Amazon website. Authors can upload their manuscripts, set their prices, and earn royalties on each sale. KDP offers various tools and resources to help authors format their books and promote them effectively. The platform supports multiple genres and allows for both eBooks and paperback publishing. With KDP, writers maintain control over their content and can update their books whenever needed.
