After yesterday's big announcement that the Kindle was going to work with Overdrive, there were more questions than answers. Today, more details are emerging, although the picture is far from complete. One of the big answers came from the Overdrive blog, which clarified:
Your existing collection of downloadable eBooks will be available to Kindle customers. As you add new eBooks to your collection, those titles will also be available in Kindle format for lending to Kindle and Kindle reading apps. Your library will not need to purchase any additional units to have Kindle compatibility. This will work for your existing copies and units.
Overdrive books won't be available until this coming fall, and by then, many more answers should be available.
In the meantime, the New York Times wrote an article about the Kindle coming to libraries and Kasson Public Library's own Ingvild Herfindahl is quoted.
