Presents perspectives on migration from all of the major social science disciplines, as part of the ongoing attempt to synthesize a general theory of migration. A section on general perspectives contains papers on areas such as a systems approach to a theory of rural-urban migration, political refugees, theories of international immigration, and a general theory of migration in late capitalism. A section on disciplinary perspectives looks at subjects including long- run economic effects of immigration, the formation of new states as a refugee-generating process, and recent European migration. Articles were originally published between 1958 and 1993. No index. Annotation copyright by Book News, Inc., Portland, OR
