This could be a fun opportunity for any teachers who create their own classroom materials (which is most teachers, right?): Amazon has released a Beta version of it Kindle textbook Creator, which allows authors to convert PDFs into eBooks and include visual content like graphs and charts. The eBook created is supported across multiple platforms, including Kindle Fire, iOS, and Android devices. This may not be the best solution for language learning “workbooks”, but we’ll let you try it out and report back to us! Authors retain the rights for their content and can earn up to 70% in royalties.
