Here (http://www.livejournal.com/tools/memories.bml?user=rivkat&keyword=Fan+fiction+and+the+law&filter=all) in my memories I've linked to the available bibliography on the subject. There's a student note published a year or so ago that updates my article, though I don't agree with everything she says. My opinion is that web fanfic is highly likely to be fair use; zines are a tougher issue, though after Wind Done Gone probably also okay. Art and vids are trickier, but the written word has a privileged status in fair use these days when it comes to creative response to copyrighted materials.
