I teach negotiations all over the world and this is the book I like to recommend. I also like "Negotiate This" by Herb Cohen and "Predictably Irrational" by Dan Ariely. I have read so many negotiation books written by professors. While most are enlightening, they are mostly difficult to read. These 3 books are enjoyable to read so I have typically handed out this book as something they students should read when I teach and recommended the others. However, I teach negotiations for an oil company, not at the university, so my style is quite a bit different.
