From Written Word Media:
Kindle Unlimited has revolutionized the eBook experience for both readers and authors. Last year we took a look at how Kindle Unlimited affects authors and publishers. This year we want to take a closer look at the habits of KU readers compared to non-KU readers, and what that means for authors whose titles are enrolled in KU. We surveyed almost 1,000 readers and analyzed the results to find out what the takeaways are for the author community.

The service currently costs $9.99/ month, and there are over 1.4 million titles available to enjoy. Most of the books available are either classics or titles published through Amazon imprints and Kindle Direct Publishing. This means that if, as a reader, you most frequently read titles by popular, best-selling authors, you may not find the names you recognize available in the KU library. To date, none of the major publishers have opted to make their titles available through KU.
KU readers can read as many books as they want per month. The one limitation is that readers can only have 10 Kindle Unlimited books downloaded to their devices at a time. This means that readers can’t “hoard” books the way that they may normally feel inclined to.
