Worldreader.org is experimenting with the notion that e-readers are libraries you can fit in your pocket. This organization is starting a new campaign that would deliver e-readers, like Barnes and Noble's Nook and Amazon’s Kindle, to children in Ghanaian schools. The e-readers will serve as multi-purpose textbooks by providing instant access to the thousands of books now available digitally. e-Readers require a high initial investment as well as Internet access. However, they take up very little space and do not require shipping and production costs that would make it expensive to send a library’s worth of reading materials to remote regions in third world countries. Assuming that the devices don’t break, it's a brilliant way of ensuring that students can read the most recent editions and releases of books via digital storefronts.
