ABSTRACT
No watertight definition exists of what planning is all about. This is not surprising when one considers, in planning practice, the very different types of work involved in the planning of different spatial units from regional level down to town centre; in planning education, the wide variations in course content from one school to another; in planning research, the wide range of subjects and techniques which produce results relevant in some way to planning. Therefore, before going on to discuss the literature of planning, it is appropriate to attempt, not a definition, but an indication of the content and the boundaries of the subject.
