In its response, Bloomsbury said Rowling "had never heard of Adrian Jacobs nor seen, read or heard of his book Willy the Wizard until this claim was first made in 2004, almost seven years after the publication of the first book in the highly publicised Harry Potter series.

"Willy the Wizard is a very insubstantial booklet running to 36 pages which had very limited distribution. The central character of Willy the Wizard is not a young wizard and the book does not revolve around a wizard school."
