Printing and the Mind of Man (PMM) is a landmark publication in the study of books and their place in culture. First published in 1967, PMM was based on the 1963 exhibitions of the same name held in London which sought to examine the the impact of printed books on the development of western civilisation. It included over 650 examples of printing and printing technology documenting the influence of print on the development of Western world. It soon became an important reference work for book collectors and remains an indispensable resource for booksellers, librarians and bibliophiles today. You can find very fine illustrated copies of PMM, complete with protective slip case, here.
