Nine papers from an April 1996 colloquium held in Amsterdam address moral, political, historical, social, and legal aspects of the exclusion of certain people from citizenship in industrialized countries. The contributors discuss state policies concerning immigration, refugees, asylum, naturalization, and the incorporation of newcomers and indigenous people. Some contributors offer schemes for long-term, internationally coordinated migration and incorporation policies. Western European countries, Canada, and Australia receive particular attention.
