Her first novel for adults is due in September, but JK Rowling isn't ready to leave behind the world of her most famous creation. The author has confirmed she is hard at work on her long-promised encyclopedia of theHarry Potter world.
In the "frequently asked questions" section on her new author site, Rowling said that "for a long time I have been promising an encyclopedia of Harry's world, and I have started work on this now – some of it forms the new content in Pottermore. It is likely to be a time-consuming job, but when finished I shall donate all royalties to charity."
Four years ago Rowling took small American publisher RDR Books to court over its plans to publish the Harry Potter Lexicon, an unauthorised A to Z of the Potter stories. Rowling called the book "wholesale theft of 17 years of my hard work", and won the case.
When Rowling published the Harry Potter fairytale spin-off The Tales of Beedle the Bard for charity in 2008, she sold 368,000 copies in just three days.
