If you're new to the Harry Potter universe and befuddled by words like "muggle" and "squib," the author of the popular book series, J.K. Rowling, is here to help. She's announced that she's finally assembling a long-awaited Harry Potter encyclopedia.

Rumors of the tome have been floating around for a few years now, ever since Rowling and the distributor of the 'Potter' films, Warner Bros., filed a copyright infringement suit against the publisher of the unofficial "Harry Potter Lexicon" back in 2007.

During her testimony in the case, Rowling said she was writing her own companion book, telling the judge, "I think [the 'Lexicon' is] atrocious. I think it's sloppy. I think there's very little research. [It] constitutes wholesale theft of 17 years of my hard work."

She also told the judge in that case that she's "made enough money," which could be why, when announcing her own Potter encyclopedia on her website, Rowling said, "It is likely to be a time-consuming job, but when finished I shall donate all royalties to charity."
