Originally published in 1911, this book contains a list of the books in the collection of St Catharine's College, Cambridge, which were printed before 1521. Bilderbeck supplies a brief history for some of the more interesting books and the people who donated them to the college, as well as a description of the condition of each volume and its binding, and three plates showing the decorative bindings on several of the books in the collection. This book will be of value to anyone with an interest in early printed books and in early modern publishing.
