Although this paper is a sequel to an earlier review of Latin American urban research (1965b), the volume and sophistication of work in the urban field during the past five years have made it advisable to limit the number of themes addressed, to dwell on complementary or discrepant approaches to certain central issues, and to suggest comparative perspectives. The first section, restricted to Spanish America, attempts to clarify some colonial antecedents of contemporary phenomena and is even less systematic than the other four sections as a research inventory. Attention to nineteenth-century developments is limited to references in Section V. The review of contemporary themes is weighted toward anthropological, sociological, and general institutional matters; the author has no credentials for prowling the arctic realms of economics, political behaviorism, and geographic place theory.
