Rowling filed a lawsuit against RDR Books in U.S. District Court in Manhattan, arguing that the lexicon violates the copyrights on her popular boy wizard novels.
"I took no pleasure at all in bringing legal action and am delighted that this issue has been resolved favorably," Rowling said in a statement Monday. "I went to court to uphold the right of authors everywhere to protect their own original work. The court has upheld that right. The proposed book took an enormous amount of my work and added virtually no original commentary of its own. Now the court has ordered that it must not be published. Many books have been published which offer original insights into the world of 'Harry Potter.' 'The Lexicon' just is not one of them."
