J.K. Rowling testified before a full packed courtroom in a lawsuit to block the publication of a Harry Potter lexicon as she tells the judge that the book amounts to a “wholesale theft” of almost 20 years of her writing career. She claimed copyright infringement last year upon suing Michigan-based RDR Books to stop publication of Steven Vander Ark’s “Harry Potter Lexicon.” Steven Vander Ark is the one behind the popular lexicon website and RDR wanted to publish a printed version of the website and charge 24.95 dollars. Rowling said that the printed version is just a copy or rearrangement of her own material that it almost amounted to plagiarism. But RDR defended that the lexicon would serve as a reference guide to organize and discuss the complicated world of Harry Potter.
