Query: What? You don't have this book yet?

I am a professional Web developer and designer working for a large hospital and many smaller clients. Here's what I say to members of my team and to freelancers coming to me in search of work:"I don't even want to see your portfolio if you haven't read this book."It is not the ONLY book of smart design, but it is THE book on smart design.Another one that I highly recommend, not as a substitute for "Don't Make Me Think," but as a go-along, is "Designing the Obvious: a common sense approach to web application design" by Robert Hoekman Jr.If you can only afford one, get "Don't Make Me Think," or don't bother showing your portfolio to me.
