Book excerpt: Images and accounts of the Mexican - US migration process and the border region abound. Representations of border crossers, plans for the construction of a security fence, the shifting economic relationship between the US and its southern neighbors, and the changing character of the Rio Grande area have played a pivotal role in shaping contemporary political discourse. The Politics, Economics, and Culture of Mexican-US Migration, which has attracted contributors from four different countries, offers multidisciplinary and interdisciplinary evaluations of these developments. It also considers the impact of migration in both the US and Mexico. Some of the contributions are case-studies, while others have a broad 'survey' character. All place the current debate about migration and the changing nature of the north American continent within its wider context in a way that is of relevance and interest to both the specialist and the more general reader.
