This book appeared in American, British and French editions but is no longer available, although you might find the Penguin paperback in used bookshops. This was my first book, a critique of appropriate technology of the 1970s, aka the “small is beautiful” movement. I was active in alternative technologies, but I was uncomfortable with much of the polemic associated with AT, and this book is the result. When Penguin reissued Paper Heroes in 1991, I added an Epilogue, for it seemed to me that appropriate technology was reappearing in a new guise: sustainability. Today, twenty years later, that is truer than ever, and many of my observations remain pertinent.
