Thanks to both commentators for the Ross King suggestion. My Yale UP copy of The Bookshop of the World is indeed a paperback and looking at it again I can agree that the print is small by common trade paperback standards today. Perhaps it needed to be produced as a larger format paperback.

And the two new suggestions are very welcome too. While we are on the topic of the history of books and printing, I have an additional title to suggest that I read two years ago: The Paper Chase by Joseph Hone, a case-study of a clandestine printing operation in Queen Anne's London. Cheers! and Happy New Year
