This bibliography suggests a number of introductory readings that will enable regional and urban planners to understand the systems approach. The main focus of the research study that gave rise to this review of the literature was on establishing ways in which decisionmakers in regional planning could be helped in making their choices. The bibliography is divided into six sections. These sections present references on the systems approach to regional planning, systems analysis, design and the planning process, general systems theory, models, and mathematical and technical background sources. In the majority of subsections, one or two of the references are annotated. The reader who studies at least one of the annotated references from each subsection will develop a broad and rigorous base on which to build his knowledge. The extra references in each section provide guidelines for those who wish to fill out their knowledge of particular aspects of the field. (Author/DN)
