Author J.K. Rowling revealed on her website that she has begun working on a Harry Potter encyclopedia.

She wrote: “For a long time I have been promising an encyclopaedia of Harry’s world, and I have started work on this – 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.”

In past interviews, she has estimated that this project could take ten years to complete. When Rowling first began talking about this project, she envisioned a book that will include some of her unpublished writing notes, the histories of minor characters and more details about the wizarding world in a post-Voldemort era.

Back in 2007, she told The Today Show: “Dean Thomas had a much more interesting history than ever appeared in the books.”

In the mean time, fans can enjoy the new Harry Potter eBooks, log on to Pottermore or look forward to the Rowling’s first adult book for distractions. Doesn’t this feel similar to the wait for the Harry Potter books all over again? (via Entertainment Weekly)
