There are several charities that distribute paper books to children in Africa ( Books for Africa is one example), but Worldreader has taken it to the next step. They distribute e-readers and e-books to children in Africa. They don’t do it alone, both USAID, Amazon, and several publishers are involved, as well as the Goverment of Ghana.
When I first read about it, I was a bit surprised but it fit. In many African countries they jumped directly to cellphones, so why not e-readers?
