Book excerpt: This encyclopedia is a unique collection of entries covering the arrival, adaptation, and integration of immigrants into American culture from the 1500s to 2010. Few topics inspire such debate among American citizens as the issue of immigration in the United States. Yet, it is the steady influx of foreigners into America over 400 years that has shaped the social character of the United States, and has favorably positioned this country for globalization. Immigrants in American History: Arrival, Adaptation, and Integration is a chronological study of the migration of various ethnic groups to the United States from 1500 to the present day. This multivolume collection explores dozens of immigrant populations in America and delves into major topical issues affecting different groups across time periods. For example, the first author of the collection profiles African Americans as an example of the effects of involuntary migrations. A cross-disciplinary approach—derived from the contributions of leading scholars in the fields of history, sociology, cultural development, economics, political science, law, and cultural adaptation—introduces a comparative analysis of customs, beliefs, and character among groups, and provides insight into the impact of newcomers on American society and culture.
