Some of the books that i am most likely to disparage are business fables. I find it quite cloying and repellent, actually. When a co written book comes off er, it can be very, very effecte. One that i continue to recommend is creativity ink by ed catmall who was president of pikar. Because it is self deprecating and points to failures of his e it's an effective way of teaching people how to manage creative people which we were all interested in knowing about.
