This visual reference book builds on the depth of coverage of the original edition by taking full account of the many varied and important developments that have taken place in the design world over the past few years. The book shows how design has responded to economic, technological and social change and how it is responding to new challenges. By identifying and isolating the key elements of design, this book attempts to make sense of the many elements that have affected design from the mid-19th century to the 1990s.
