Kindle Unlimited is a subscription service offered by Amazon that provides readers with access to a vast library of eBooks, audiobooks, and magazines. Subscribers pay a monthly fee to gain unlimited reading access to a wide range of digital content from various genres, including fiction, non-fiction, romance, mystery, and more.
Authors who choose to publish their books on Kindle Direct Publishing (KDP) have the option to apply for inclusion in the Kindle Unlimited program. However, it's important to understand that this program comes with exclusivity requirements. During the contract period, typically around 90 days, books enrolled in Kindle Unlimited cannot be published on any other platform besides KDP. As a result, participation in Kindle Unlimited is limited to authors who publish directly through KDP.
If you're currently enrolled in Kindle Unlimited but wish to expand your distribution through PublishDrive, the process is straightforward. You'll need to wait until your contract period with Kindle Unlimited ends, and then you can upload your books to PublishDrive without any restrictions.
