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.

Religious debates over the Harry Potter series: Religious debates over the "Harry Potter" series of books by J. K. Rowling are based on claims that the novels contain occult or Satanic subtexts.  A number of Protestant, Catholic, and Orthodox Christians have argued against the series, as have some Shia and Sunni Muslims.  Supporters of the series have said that the magic in "Harry Potter" bears little resemblance to occultism, being more in the vein of fairy tales such as "Cinderella" and "Snow White", or to the works of C. S. Lewis and J. R. R. Tolkien, both of whom are known for writing fantasy novels with Christian subtexts.  Far from promoting a particular religion, some argue, the "Harry Potter" novels go out of their way to avoid discussing religion at all.  However, the author of the series, J. K. Rowling, describes herself as a practising Christian, and many have noted the Christian references which she includes in the final novel "Harry Potter and the Deathly Hallows".

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.
