JK Rowling to judge: 'Don't let them rip off my books'

A three-day trial over an unauthorised Harry Potter encyclopaedia ended with a flash of anger from JK Rowling.

The best-selling British author returned to the witness stand in New York and told a judge that if he allowed the fan-written lexicon to be published, it would clear the way for countless rip-offs of her books, as well as the work of other popular authors.
