Potter fan weeps in copyright battle

A Harry Potter fan in the US who sought to publish an encyclopaedic guide to the novels broke down and cried on the witness stand tonight as he faced his idol JK Rowling in court.

The British author sued Steven Vander Ark and publisher RDR Books last year, claiming that their Harry Potter Lexicon – based on Mr Vander Ark’s fan website - infringed on her copyright.
