This book was presented on the occasion of Christopher de Hamel's sixtieth birthday, and celebrates his many accomplishments during his years at Sotheby's and more recently as the Gaylord Donnelley Fellow Librarian of the Parker Library at Corpus Christi College, Cambridge. Christopher de Hamel has described more medieval manuscripts than any other living scholar, and the sale catalogues that have come from his hands set new standards of quality and stimulated new generations of collectors, both institutional and private. This book is a tribute to his learning, his industry, imagination, spirit and good fellowship and his capacity to inspire others. Among the contributors are collectors, colleagues, librarians, curators, students of book history and scholars. The contributions are divided under the rubrics Books, The Book Trade and Collectors and Collecting, composing a varied collection of 40 highly interesting articles, including an introduction on Christopher de Hamel and a bibliography of his writings.
