Some of his more recent ones have been broken into chapters, BJ. I actually prefer his Discworld novels not to have them as he alwyas has quite natural breaks in the text anyway. However, my Mam can't read the Discworld novels because most of them have no chapters - it really gets to her!
I'd also love to be stuck in a lift with SM, simply to ask her how she managed to turn a mediocre series of vampire stories into such a hugely popular money-spinner - LOL!
