This volume is a collection of essays about editions and the materials involved in their making. Elucidating the material characteristics ? e.g. the appearance and composition of the material and the different written layers, the arrangement and features of handwritten and printed books can provide clues about the origin of a text. Thirty-five individual contributions ? ranging from Bible transmission in antiquity, medieval manuscripts to the sketch books of modern authors ? explore how such material features are studied, processed and presented within the framework of edition-making.
