Products liability is perhaps the most contested and confused area of American private law. It affects every American who purchases or uses any product. It is the object of late-night talk show jokes and politicians' stump speeches. Yet, like many subjects discussed by politicians and TV stars, products liability is more subtle and multi-layered than they make it appear. This concise hornbook is designed to unpack these subtleties and allow the reader to understand current American products liability doctrine and to intelligently participate in debates about proposed reforms.
