Book excerpt: Bringing an empirical, objective approach to a topic that has often been the source of emotional and uninformed controversy, Gentrification, Displacement and Neighborhood Revitalization provides an introduction to major issues in urban revitalization, new research findings, and a discussion of theoretical perspectives. This is the first broad-based survey of a scattered literature that has not been readily accessible. The book's comprehensive introduction leads to informative analyses of new research by sociologists, planners, geographers, and urban studies faculty. A concluding essay examines the present state of knowledge about gentrification and discusses its implications, suggesting future developments and trends.
