We like David Gibson's book The Wayfinding Handbook: Information Design for Public Places for what are probably all of the wrong reasons. It's clearly intended as a guide for signage designers, and no doubt extremely useful to such folks. But we'd argue that we aren't alone in appreciating environmental information design (and information design in general) on its aesthetic merits; the colour, clarity and iconic nature of the medium connects with a viewer in a similar way as it does when these same traits are applied to, say, the works of Mark Rothko. We also viewed the book as a lens for focusing our appreciation of such design as viewed in real life. And we liked the fact that the book is a paperback under $20, in a world full of $60 coffee table crushers.
