Despite the fact that J.K. Rowling relied on emotional, rather than legal
reasons for not wanting the publication of a guidebook about the Harry Potter universe, called the Harry Potter Lexicon
to go forward, it appears that a judge was convinced. The judge has halted the publication of the Lexicon
, saying that it violates Rowling's copyrights and did not establish a fair use defense. Hopefully the book publisher will appeal, as there seems to be some questionable statements in the ruling:
"because the Lexicon appropriates too much of Rowling's creative work for its purposes as a reference guide, a permanent injunction must issue to prevent the possible proliferation of works that do the same and thus deplete the incentive for original authors to create new works."
It's quite difficult to see how the publication of the Lexicon, which would only encourage more fans to dig even deeper into the Harry Potter universe somehow "depletes" the incentive for the original author to create new works. The Lexicon does nothing more than add more value to the rest of the Harry Potter books, and to deny its publication seems like a travesty of a broken copyright system.
