MATHEMATICAL REVIEWS "This is a textbook for graduate students who have had an introduction to abstract algebra and now wish to study noncummutative rig theory...there is a feeling that each topic is presented with specific goals in mind and that the most efficient path is taken to achieve these goals. The author received the Steele prize for mathematical exposition in 1982; the exposition of this text is also award-wining caliber. Although there are many books in print that deal with various aspects of ring theory, this book is distinguished by its quality and level of presentation and by its selection of material....This book will surely be the standard textbook for many years to come. The reviewer eagerly awaits a promised follow-up volume for a second course in noncummutative ring theory."
