Summary

Enrolling an eBook in KDP Select adds it to Kindle+ (the subscription Amazon renamed from Kindle Unlimited), where reads are paid from the KDP Select Global Fund, and unlocks Free Book Promotions and Kindle Countdown Deals. The catch is exclusivity: for each 90-day term the eBook can only be distributed through KDP and public libraries, though print and other formats can be sold elsewhere. Enrollment renews automatically unless you turn renewal off, and you can only cancel within three days of the start of a term.
