It does sound like a neat idea, and something I'd be interested in reading. (Don't think I'd be much help with info as I've only read most of the series once, but it's something I've always wanted to do for the Anne Rice books, and I have substantial notes for those. I thought I was the only one who did stuff like this!) Agree with mneiai that LJ might be a good place to set it up - the Memories system could be handy for organising the information in different categories and sub-categories.
