Book excerpt: Barbara H. Rosenwein's bestselling survey text continues to stand out by integrating the history of three medieval civilizations (European, Byzantine, and Islamic) in a lively narrative that is complemented beautifully by full-color plates, maps, and genealogies. The fourth edition begins with an essay entitled "Why the Middle Ages Matter Today," and the book now covers East Central Europe in some depth. New plates and maps have been added along with a new "Seeing the Middle Ages" feature. The sections for further reading have been updated, and ancillary materials, including study questions, can be found on the History Matters website (www.utphistorymatters.com).
