The fifty-third 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. The volume opens with unpublished lectures by one of the twentieth century's most distinguished bibliographers, R. B. McKerrow, followed by another of G. Thomas Tanselle's foundational essays on the description of books, this one on the bibliographical concept of format. Other articles trace the invention of the Hinman Collator, explore the nature of bibliographical reasoning, including the use of statistics, propose attributions to Samuel Richardson, and investigate puzzles in particular works from the Middle Ages through the nineteenth century. The articles and their authors are: ""The Relationship of English Printed Books to Authors' Manuscripts during the Sixteenth and Seventeenth Centuries (The 1928 Sandars Lectures),"" R. B. McKerrow, edited by Carlo M. Bajetta, Catholic University of Milan and University of Genoa; ""The Concept of Format,"" G. Thomas Tanselle, Guggenheim Foundation; ""The Calculus of Calculus: W. W.
