There is a spectacular amount of confusion over this book. I'm in personal contact with two of the three authors and even I can't get a straight answer about whether the book is even coming out!
However, if it does come out next week, it will look quite different from the three previous Encyclopedia editions. Yes, of course there will be references to the more recent shows, but the book will not be nearly the comprehensive reference book that the earlier volumes were. Instead, it will be set up as more of a fun, light read with lots of lists and lots of pictures.
If it comes out.
