Tim Wu, a Columbia Law Professor, led a panel May 1st at OnCopyright 2008.  The panel talked a lot about the JKR vs RDR Books lawsuit. .Here is some information from a summary on the conference at EContent Magazine:

He planted the seeds for his group’s discussion by familiarizing the conference audience with the story of Steve Vander Ark, the creator of The Harry Potter Lexicon, an online encyclopedia that is a companion to the Harry Potter children’s book series. The Lexicon gained widespread news coverage in recent months when Potter author J. K. Rowling took Vander Ark to court for copyright infringement over a proposed published edition of the Lexicon. Wu played an official Harry Potter podcast in which other members of the Harry Potter fan community ostracized and effectively banished Vander Ark from their ranks. Wu’s question to the panel was, “Why are Harry Potter fans disowning Vander Ark?” The panel’s answer was that the fan community needs to disassociate itself from anyone who goes to far in appropriating creative content for fear that their own access to that content might dry up. The panel also noted that Vander Ark’s attempt to turn his online Lexicon into an ink-and-paper book was his ultimate undoing.
