Popular children’s author J.K.Rowling testified in a New York Court today to block the publication of soon to be released dictionary called the Harry Potter Lexicon based on her book series.

Rowling says the Lexicon book by author Steven Vander Ark amounts to copyright infringement and that she has planned to publish her own Harry Potter dictionary and give the proceeds to charity.

Vander Ark defends that his work amounts to “fair use” of Rowlings books as allowed by federal law for research, criticism, and commentary.

The case is Warner Bros. Entertainment Inc. v. RDR Books, 07-cv-09667, U.S. District Court, Southern District of New York.
