This volume presents a catalogue and study of printed books produced between 1501 and 1540, held in the theological library of Leuven University. Gistelinck and Sabbe investigate typographic techniques, illustration, bindings, and provenance, giving insight into the early book trade and scholarship in early modern Europe. Gistelinck and Sabbe reconstruct the production, circulation, and reception of printed books in the early sixteenth century at Leuven. They analyze printing workshops, typographic composition, illustration techniques, and original bindings, as well as how these books were used by theologians and students. The book provides a detailed catalogue of surviving editions with precise bibliographic references and examines the impact of printing on the dissemination of humanist and theological ideas. The authors also discuss collecting and exchange practices, and the role of Leuven as an intellectual center.
