Most the nineteen contributors presented papers at this series of seminars, but some have been rewritten, others substantially revised, and several have been commissioned especially for this book. Four current policy issues are examined: provision and pedestrians; jobs for the inner cities; the homeless and the relationship between planners and developers. For each topic contributors were chosen who could approach the problem from a different point of view, the aim being to explore each topic with direct statements and straightforward arguments leading therefore to a more stimulating breadth of this view rather than a bland overview.
