J.K. Rowling wants to be sure she's the only one making money off her Harry Potter empire. So she's suing the publisher of a print version of the popular Potter fan website, The Harry Potter Lexicon.
What's funny about the lawsuit is that Rowling admits to using the website to fact-check her own work! But she says making a print version out of it is a copyright infringement.
How a print version is different, we don't know. But if she sues, she should use that money to hire a fact checker on her own books, rather than continue to use the Lexicon.
