"This book was conceived in the context of Turning Over a New Leaf : Manuscript Innovation in the Twelfth-Century Renaissance, a research project directed by Erik Kwakkel and established at Leiden University from 2010 to 2015. It fulfills the desire of both editors to make available a synthesizing study devoted to all major subject areas of twelfth-century manuscript culture in the West. In the fall of 2014 a group of leading scholars was invited to write chapters for this book. The aim was not only to present the current state of research in the various subject areas, but also to highlight the possibilities for new directions in the future" --
