Following earlier commentage I think I've sorted out my amazon wish list link. It was directing people not to my wish list earlier but to here. I wish to assure my readership (specfically Dr T) this book is 100% not required! The only person I can think who would be interested in it is Claire (Hmm wonder when we're get some button realted news). I wonder if anyone else has had wish list links go aray to publications that could concern?
