Amazon is testing out a ‘Spotify for Books’ service

Amazon is about to change the way we acquire books once again. According toGigaom, members of the Kindle Boards discovered a page on Tuesday which appears to reveal an upcoming eBook subscription service called “Kindle Unlimited” which would allow subscribers to access over 600,000 titles and thousands of audiobooks “on any device” for $9.99 a month. Although the test pages have since been removed, you can still find them on Google Cache.

At the time of writing, a page titled “KU Test” is still available on the Amazon website, listing 638,424 titles which are presumably going to be part of the service if and when it launches. As Gigaom points out, many of these titles are also available through Amazon’s lending library, which allows Kindle owners to borrow one eBook free of charge every month.

There doesn’t appear to be any indication as to whether a Prime membership would entitle an Amazon customer to Kindle Unlimited, but taking into account the recent launch of Prime Music, it wouldn’t be a shock to see Amazon give Prime members a free subscription, or at least a discount to the service.

We’ll be keeping an eye out for any more signs of Kindle Unlimited resurfacing in the coming days.
