This volume gathers established and new scholars working on North American immigration, transmigration, internal migration, and citizenship whose work analyzes the development of migrant and state-level institutions as well as migrant networks. With contemporary migration research most often focused on the development of transnational communities and the ways international migrants maintain relationships with their sending region that sustain the circular flow of people, ideas, and traditions across national boundaries it is useful to compare these to similar patterns evident within the terrain of internal migration. To date, however, international and internal migration studies have unfolded in relative isolation from one another with each operating within these distinct fields of expertise rather than across them. Although there has been some important linking, there has not been a recent major consideration of human migration that works across and within the various borders of the North American continent. Thus, the volume presents a variety of chapters that seek to consider human migration in comparative perspective across the internal/international divide. Marc S.
