This book is the first-ever reference to the four seventeenth-century editions of William Shakespeare's collected plays known as the folios. Along with the quartos, these works are highly valued as the earliest surviving texts of the plays and are frequently cited and discussed in textual studies and general criticism. As an introductory study of these editions, this book focuses on how the folios have traveled over time, where they can be found today, and how they have been valued monetarily. It is the first census of Shakespeare folios conducted in the last fifty years, and it is the first handbook to these important texts ever compiled. The book provides a wealth of information about the folios in a format that can be quickly and easily accessed. It describes the four editions, explains their significance, and traces their market value over time. In addition, a census shows which libraries in the United States hold folios, the chronological movement of the copies to the U.S., and some specific details on each copy. Also included are a biographical dictionary, which offers information on publishers, editors, collectors, and major scholars important to the folios, descriptions of famous copies, a list of donors, discussions of folio lore and bindings, and a bibliography. An essential reference for all Shakespeare collections, this book will be an valuable resource for courses in Shakespearian history and the history of books and printing. It will also be an important addition to both academic and public libraries.
