Drawing extensively on archival research, The Late Cantos of Ezra Pound critically explores the textual history of Pound's late verse, namely Section: Rock-Drill (1955) and Thrones (1959). Examining unpublished letters, draft manuscripts and other prepublication material, this book addresses the composition, revision and dissemination of these difficult texts in order to shed new light on their significance to Pound's wider project, his methods and techniques, and the structures of authority--literary and political-that govern the meaning of his poetry. Illustrated by reproductions of archival documents, The Late Cantos of Ezra Pound is an innovative new study of one of the most important poets of the 20th century.
