There was quite a bit of excitement generated by the fact that Harry Potter author J. K. Rowling is working on a new, completely separate, adult novel that she’ll be finishing this coming fall. And Pottermore will be open to the public very soon, I believe. So there’s a ton of awesome things going in this arena and now we’ve got one more!
J. K. Rowling is writing the long-awaited Harry Potter encyclopedia! (Or, according to Ted Mosby, she’ll be writing an encyclopaedia.)
This was written on her personal website, although the exact link is apparently being elusive:
For a long time I have been promising an encyclopaedia of Harry’s world, and I have started work on this now. Some of it forms the new content in Pottermore.
Chances are this won’t be released any time soon; I recall her saying a while back that doing something like this and compiling all the information she has on the Potterverse wouldn’t be a priority for her. And I’m not surprised, especially given that she’s probably giving her new novel some more attention at the moment.
Still, something for us Potter nerds to be excited about!
