If you are a steward or plan to become one, I recommend picking up this book while it is available. Every few years they publish a new edition of The Legal Rights of Union Stewards but only print very few copies and then it's nearly impossible to find. The publisher has about 80 copies right now and they only cost 20 bucks plus $5 shipping.
