This paperback Re-issue is in very good condition, with crisp clean pages and tight binding. There is minor signs of usage to the front cover showing bumping and slight raising of its front corners.Professor Postan\'s work on the social and economic history of the Middle Ages has had an enormous influence upon the study of the subject. His essays represent his major contribution and are an invaluable addition to the literature. Twenty-two essays are gathered together into two volumes. Previously published elsewhere, many in obscure places, over a period from 1928 to 1972, they are still greatly used and referred to today; their appearance in this more accessible form will be warmly welcomed by a wide range of students and scholars in all branches of medieval and economic history as well as by social scientists and economists generally. This volume contains such seminal pieces as The economic foundations of medieval society, The rise of a money economy, The chronology of labour services and The charters of the villeins.
