I can remember reading Ralph Caplans “By Design” with great excitement when it first came out. Since then I have tried at various times to get hold of it without success. It’s been out of print since 1992. So I was pleased to see that there is a new updated version available now. There is a whole lot of stuff about this at Core77, with extracts and an interview with Caplan. If you are interested in design as a wide ranging humanistic enterprise, read this and then order the book. It is a pleasure.
