Eisenstein 1983 -- "Most studies of printing have, quite rightly, singled out the regular provision of title pages as the most significant new feature associated with the printed book format. How the title page contributed to the cataloguing of books and the bibliographer's craft scarcely needs to be spelled out. How it contributed to new habits of placing and dating, in general, does, I think, call for further thought."
