Just discovered this book on Amazon: The Library: An Illustrated History.
“The Library tells the story of libraries and of the changing form and function of the book from era to era, whether clay tablets, parchment sheets, papyrus scrolls, glossy paper, recording tape or silicone chips. At the heart of the story of libraries and books is the story of the reader, who also has changed from era to era. Profusely illustrated, with fascinating is a comprehensive look at libraries that will interest book lovers and librarians.”
The book is indeed very richly illustrated. The sections on ancient libraries is especially interesting. There is not a lot written on the subject, as far as I know.
