HP encyclopaedia to go on sale

A new version of the Harry Potter encyclopaedia which JK Rowling went to court to get banned, is due to hit the shelves later this month.

Back in September, the Harry Potter author won her court case to stop Steve Vander Ark publishing his 400-book about the world of the boy wizard.

But Mr Vander Ark says he has spent the last six months changing his book.

The 50-year-old Harry Potter fan says it now meets all the requirements set out by the court.

For many years JK Rowling had said she wanted to write her own encyclopaedia, and give the money raised from the book to charity.

And the judge in New York ruled that the publication of The Harry Potter Lexicon would cause serious damage to her work as a writer.

But Mr Vander Ark says during the court case he found out what he was allowed to write in the book, which is called The Lexicon: An Unauthorised Guide to Harry Potter Fiction and Related Materials.

"That was not clear before. There was no law on the books that made it clear what was acceptable and what wasn't," he said.
