Glazer, Nathan. "Ethnicity - North, South, West." Commentary 73 (1982): 73-79.
Excerpt: Twelve years ago, Daniel P. Moynihan and I, reviewing the condition of politics in New York City for the second edition of Beyond the Melting Pot, described two models of group relations which we dubbed “Northern” and “Southern.” Both models, we wrote, rejected the idea that the fate of ethnic groups and races in the United States was to acculturate to a common American mean, and both affirmed the reality of group distinctiveness. But otherwise the differences between the two models were striking: In the Southern model, society is divided into two segments, black and white.
