Warner Bros. Entertainment Inc. v. RDR Books: Warner Bros.  Entertainment, Inc. and J. K. Rowling v. RDR Books, 575 F.Supp.2d 513 (SDNY 2008) is a copyright lawsuit brought on 31 October 2007 by the media company Warner Bros. and "Harry Potter" author J. K. Rowling against RDR Books, an independent publishing company based in Muskegon, Michigan.  Lawyers for Rowling and Time Warner argued that RDR's attempt to publish for profit a print facsimile of "The Harry Potter Lexicon", a free online guide to the "Harry Potter" fictional universe, constituted an infringement of their copyright and was not protected by the affirmative defense of fair use.  The trial was held from 14–17 April 2008 in the United States District Court for the Southern District of New York.  In September 2008, the court ruled in Rowling's favor, and publication of the book was blocked.  In 2009, RDR Books released an edited volume, eliminating the problematic long quotes found to be infringing.

Fictional universe of Harry Potter: The fictional universe of British author J. K. Rowling's "Harry Potter" series of fantasy novels comprises two distinct societies: the Wizarding World and the Muggle world.  The Muggle world is the series' name for the world inhabited by the non-magical majority, with which the Wizarding World exists coextensively, albeit mostly remaining hidden from the non-magical humans.  The plot of the series is set in 1990s Britain, but in a veiled and separate shadow society wherein magic is commonly used and practiced, and those who can use it live in self-enforced seclusion, hiding their abilities from the rest of the world.  The term "Wizarding World" refers to the global wizard community that lives hidden in parallel with the Muggle world; the different terms refer to different communities within the same area rather than separate planets or worlds.  Any new works taking place in this universe are released under the "J. K. Rowling's Wizarding World" brand.

Magical creatures in Harry Potter: Magical creatures are a colourful aspect of the fictional wizarding world contained in the "Harry Potter" series by J. K. Rowling.  Throughout the seven books of the series, Harry and his friends come across many of these creatures on their adventures, as well as in the Care of Magical Creatures class at Hogwarts.  Rowling has also written "Fantastic Beasts and Where to Find Them", a guide to the magical beasts found in the series.  Many of these are derived from folklore, primarily Greek mythology, but also British and Scandinavian folklore.  Many of the legends surrounding mythical creatures are also incorporated in the books.  "Children ... know that I didn't invent unicorns, but I've had to explain frequently that I didn't actually invent hippogriffs," Rowling told Stephen Fry in an interview for BBC Radio 4.  "When I do use a creature that I know is a mythological entity, I like to find out as much as I can about it.  I might not use it, but to make it as consistent as I feel is good for my plot."
