Objects in these categories are notable for their physical features in addition to their intellectual content. Maps in the collection indicate not only what was known about the world from the 16th through the 19th centuries, but what different users needed to know, presented in formats suited to their varying circumstances. About two dozen codex manuscripts, many of them illuminated, represent the arts of the book in Europe before printing, and nearly 100 incunabula are among the earliest examples of European movable-type printing. Other books, such as a complete set of Kelmscott Press titles, were collected as beautiful specimens of the book arts. Beyond their aesthetic qualities, bindings, illuminations, illustrations, and typography can also reveal the ways in which books were made and used, providing insight into topics like trade practices and education in the societies from which they came.
