This special issue of American Quarterly focuses on Los Angeles as an emblematic site through which the scholarship of American studies can be examined. As a city shaped by eighteenth-century European colonization, nineteenth-century U.S. territorial expansion, and twentieth-century migration, Los Angeles has come to embody both the hopes and fears of Americans looking to the future. It is a city in which the local is deployed in complex practices of identity and community formation within the broader networks of globalization that continue to define and redefine what constitutes America. The articles in this volume address the complexities of the city's social geography across time, particularly since World War II. The collection reflects an exciting variety of cultural studies perspectives and reveals the synergistic possibilities of current Los Angeles studies and American studies in general. American Quarterly includes interdisciplinary scholarship that engages key issues in American studies. Publishing essays that examine American societies and cultures in global and local contexts, the journal contributes to the understanding of the United States, its diversity, and its impact on world politics and culture.
