With over 1 million titles to choose from, Kindle Unlimited is by far the best book subscription service available today.

Kindle Unlimited was launched in July 2014 and it quickly became a leading contender in the e-book subscription provider race. At the time of the Kindle Unlimited launch, the other very popular Scribd  book subscription service was already up and running.

So what are the main differences and is Amazon going to rule this segment of the e-book market like it is in every other sector?

Kindle Unlimited $9.99 per month – One Month Free Trial

Pros: This service boasts a selection of over 1 million titles, making it by far the largest in the market. Kindle Unlimited also offers thousands of audio books which allow you to bounce in between reading and listening to your e-books.

Obviously, this service is compatible with all Kindle devices and by using the available Kindle apps, you can read your books on iOs, Android, Blackberry and other tablets and computers.

Cons: Even though the Kindle Unlimited service has the largest selection of books, it doesn’t include books from the Big 5 publishers Hachette, HarperCollins, Simon & Schuster, Macmillan and Penguin Random House.

If you are already an Amazon Prime customer, many of the books will already be available to you.

Amazon Kindle Unlimited

Scribd $8.99 per month – One Month Free Trial

Pros: The San Fransisco based business offers 500,000 books from over 900 publishers. And like Amazon, they have apps for the iOs, Android, Windows devices and the Kindle Fire.

Scribd also offers books from HarperCollins and Simon & Schuster, as well as giving you access to Lonely Planet guides and reference books from Wiley.

Cons: Scribd doesn’t include any audio books with their subscription.

Which One Is The Best Online Book Subscription Service?

Based on what we know, its difficult to choose the best one. The good thing is, they all come with a one month trial so you can see which one has the type of books you like to read before you join.

One thing to bear in mind with Kindle Unlimited is that it seems limited to books made available directly by the author. So we encourage you to research each service yourself to determine who has the particular range of books you are wanting.
