This book is the standard book for learning about antique books. (So I have been led to believe by UCL and the people at my work). It gives in Great detail every aspect of book production from the hand-press period, (making paper, ink, layout, type, binding etc.) as well as for 19th century book production. It answers a lot of questions and is a great referrence. It is however a little dull to read all the way through. And suffers from the problem of trying to explain in words complicated physical procedures. I found at many points I was picturing scences from Stephen Fry's documentary on the Guttenburg press. I'm glad they have it at work for reference but probably won't be getting my own copy.
