Both Amazon and Barnes and Noble announced today that all of the Harry Potter Books are available as ebooks for their Kindle and NOOK devices, respectively. At Amazon, titles must be purchased by creating an account first at Pottermore – the free-to-use “online experience” themed around the world of Harry Potter – and going through their buying processes. For NOOK, the e-books can be found through regular searching but clicking “Buy Now” ultimately redirects you to register through Pottermore and use their buying system. Pottermore is an environment where the digital world brings lovers of the Harry Potter books and lore together to share their common experiences, as well as gain new insight and information provided directly by author J.K. Rowling.
