I have bought the new edition (wouldn't you, the old one is listed at £30.99 new!), and it now has over 50 types of difficult people described. It features wonderful, positive ways to turn their difficult ways round. The one negative comment on the last edition was that it was very "layman", which is probably why the rest of us like it so much - we don't want a psychology textbook, just a few quick tips! Personally, one of the best bits of advice was in the Introduction, where Leibling says "We often talk about difficult people, labelling an entire person as `difficult' when it truth it may be just one aspect of their behaviour that we have found challenging." That struck me as a great starting point, to quote the author again, on `how to get on with people you don't get on with'. I showed my copy to a friend who is a CEO of a medium size enterprise, and she seized upon it eagerly - as she has every one of these people working for her. I enjoyed the fresh, positive approach, and Leibling's gentle humour throughout the book. Thoroughly recommended.
