In 1980, William H. Whyte published the findings from his revolutionary Street Life Project in The Social Life of Small Urban Spaces. Both the book and the accompanying film were instantly labeled classics, and launched a mini-revolution in the planning and study of public spaces. They have since become standard texts, and appear on syllabi and reading lists in urban planning, sociology, environmental design, and architecture departments around the world. Project for Public Spaces, which grew out of Holly's Street Life Project and continues his work around the world, has acquired the reprint rights to Social Life, with the intent of making it available to the widest possible audience and ensuring that the Whyte family receive their fair share of Holly's legacy. From the forward: For more than 30 years, Project for Public Spaces has been using observations, surveys, interviews and workshops to study and transform public spaces around the world into community places. Every week we give presentations about why some public spaces work and why others don't, using the techniques, ideas, and memorable phrases from William H. "Holly" Whyte's The Social Life of Small Urban Spaces. Holly Whyte was both our mentor and our friend. Perhaps his most important gift was the ability to show us how to discover for ourselves why some public spaces work and others don't. With the publication of The Social Life of Small Urban Spaces and its companion film in 1980, the world could see that through the basic tools of observation and interviews, we can learn an immense amount about how to make our cities more livable. In doing so, Holly Whyte laid the groundwork for a major movement to change the way public spaces are built and planned. It is our pleasure to offer this important book back to the world it is helping to transform.
