I have a good book at home called "Jobhunting for Pilots" that goes indepth about networking and jobhunting. I got it at a Barnes and Noble. Check the transportation section now and again and you may fond some books that are good.
The book you guys need is 'The Golden Rule of Schmoozing: The Authentic Practice of Treating Others Well' it is the best book I have found to teach you the art of networking. You can pick it up from Amazon and I do not think it is that expensive.
