This book offers a comprehensive analysis of US modernism as part of a wider, global literature. Both modernist and American literary studies have been reshaped by waves of scholarship that unsettled prior consensuses regarding America's relation to transnational, diasporic, and indigenous identities and aesthetics; the role of visual and musical arts in narrative experimentation; science and technology studies; and allegiances across racial, ethnic, gendered, and sexual social groups. Recent writing on US immigration, imperialism, and territorial expansion has generated fresh and exciting reasons to read or reread modernist novelists, both prominent and forgotten. Written by a host of leading scholars, this Companion provides unique interpretations and approaches to modernist themes, techniques, and texts.
