The fifty-second volume of Studies continues its tradition of presenting a wide range of articles by international scholars on bibliography, textual criticism, and other aspects of the study of books. Their topics, ranging in time from the Middle Ages through the twentieth century, include the scribes and manuscripts of Langland, Chaucer, and the Rolin Master; editions of Spenser and other Renaissance texts; books in Massachusetts in the eighteenth century; nineteenth- and twentieth-century periodicals; and typographical alterations in nineteenth-century books and in bibliographical classics. This volume also proposes a new system for transcribing manuscripts and provides a guide to the practice of analytical bibliography and the presentation of its results.The articles and their authors are:"The Treatment of Typesetting and Presswork in Bibliographical Description," G.
