Book excerpt: Systematically exploring the dynamic interface between Mexico and the United States, this comprehensive survey considers the historical development, current politics, society, economy, and daily life of the border region. Now fully updated and revised, the book analyzes the economic cycles and social movements from the 1880s that created this distinctive borderlands region and propelled it into the twenty-first century and a globalizing world. Richly illustrated with photographs, maps, and tables, the book concludes with an analysis of key borderlands issues that range from the environment to migration to national security.
