The work surveys the early English book trade in Westminster and London between 1476 and 1535, tracing the introduction and growth of printing and the practices of printers, stationers, and bookbinders. Presented as two lecture series, it distinguishes changes before and after 1500, examines leading figures, typographical devices, binding practices, imprints, and legal and commercial arrangements, and analyzes surviving evidence such as title-pages, devices, and unique copies to reconstruct workshops, networks, and the evolution of trade organization. Detailed plates and indices support bibliographical observations and the reconstruction of printers' identities, equipment, and business methods.
