Vander Ark's New Potter Book

Followup: Steven Vander Ark, recently banned from publishing a Harry Potter lexicon, has moved forward with a new Potter-related project. It will entail more analysis, investigating the real-world connections of the Potter universe, and less direct content from Rowling's mind -- a definite application of fair-use that shouldn't cause the legal wranglings he experienced with his Lexicon.
