Revised unathorised Potter encyclopaedia to go on sale

A new version of the Harry Potter encyclopaedia which brought multi-millionaire author JK Rowling to the verge of tears will go on sale in the UK later this month.

The 43-year-old author of the boy wizard books took Harry Potter fan and author Steve Vander Ark to court over the 400-page Lexicon, which she said constituted “wholesale theft of 17 years of my hard work”.
