This catalog provides a descriptive bibliography of books in the Ahmanson-Murphy Aldine collection at the University of California, Los Angeles, together with abbreviated notices of works not at UCLA. Handsomely produced, slipcased, and carefully annotated, this volume should become a major resource for Aldine studies and the history of the book. The Aldine Press revolutionized the production, accessibility, and use of the book. Founded by Aldus Manutius (ca 1452-1515), the press introduced a number of innovations that helped shape the development of the modern book, including italic type and the smaller, pocket-sized volume. By putting the Greek and Latin classics in a form that everyone could afford, it revolutionized scholarship: the uniform Aldine texts made comparison and collation universally available, and they were used in schools. Collectors were interested in the Aldine Press from the beginning; Jean Grolier acquired over two hundred of its publications, often having the books elegantly bound and handsomely illuminated. Since that time, the output of the Aldine Press has been sought after by scholars, book collectors, and librarians. Copies of its books are found in libraries all over the world, where they remain a prized possession and the object of much scholarly research. For thirty-two years, Franklin D. Murphy, who came to UCLA as its sixth chancellor, fostered the expansion of the Aldine collection and encouraged its growth. During the greater part of this long period he was joined in these endeavors by the Ahmanson Foundation, whose constant support permitted the collection to increase in both size and significance. Following Dr. Murphy's death, the Ahmanson Foundation continued its generous support for the expansion of the collection and, in addition, by means of a grant late in 1996, enabled the present catalog to come into existence. The Aldine Press is set in Manutius, a digital typeface specially adapted for this project by Matthew Carter of Carter & Cone, Type, Inc. from beta versions of his Miller Text and Wilson Greek. Typographic design and composition were provided by Gerald Lange of the Bieler Press in Marina del Rey, California. The book was sheet fed, printed, and bound with reinforced front and back signatures by Edwards Brothers of Ann Arbor, Michigan. The text sheet is 80lb. Mohawk Superfine; the endpapers are French Company's "Parchtone" natural. The binding cloth used for both the book and the slipcase is a Japanese book cloth (no.2504) distributed by the Campbell-Logan Bindery. The binding board is 110 point acid-free Eska board from Ecological Fibers, Inc.
