Glazer, Nathan and Daniel Moynihan. Beyond the Melting Pot: The Negroes, Puerto Ricans, Jews, Italians and Irish of New York City. Cambridge: MIT Press, 1970.
In 1970, Glazer revised and reprinted his work Beyond the Melting Pot. The book compares the five largest ethnic groups of New York City, and uses them to study politics, economics, and culture. He argues that these groups each play a distinctive role within city life.
