Subtlety, elegance, simplicity. As someone once said: "Its simple to make something difficult, but difficult to make something simple." This expression holds true for this book. This book is not for the faint of heart; it is dense with typographic information spanning a wide breadth from history to art, and theory to practice. This book is one of the few texts on typography that I flip back to when something I've typeset is bothering me. As a reference text, I have yet to see one that is quite so useful.
