Rowling is suing a guy from hp-lexicon.org for writing an HP supplementary book. Such reference guides are a rip-off and an abomination that will undermine the respect of her fans. Hope she's gonna take his money and run his website into the ground!
That'll learn him for attending conferences, thoroughly researching his material, getting his content added as extras to the WB DVD's, and then making a book with the extensive data he compiled over a span of over a decade. It's her universe, and I agree that nobody else but her should have the right to make Harry Potter related content.
