JK Rowling announced today that Harry Potter will finally be available in e-book and digital audio forms, exclusively on her own Pottermore website. Pottermore will be an interactive experience that puts readers into the world of her Harry Potter series, expected to launch in beta on July 31st and open fully to the public in October. This is the first time Rowling has allowed electronic editions of her novels, thanks to her past fears of piracy of her work. GigaOM notes that Rowling’s actions are not an option for all authors, as many writers’ contracts do not allow them to retain electronic publishing rights.
