collects important essays by Peter Middleton that show the many ways in which, in a world of proliferating communications media, poetry-making is increasingly the work of agencies extending beyond that of a single, identifiable author. In four sections—Sound, Communities, Collaboration, and Complexity—Middleton demonstrates that this changing situation of poetry requires new understandings of the variations of authorship. He explores the internal divisions of lyric subjectivity, the vicissitudes of coauthorship and poetry networks, the creative role of editors and anthologists, and the ways in which the long poem can reveal the outer limits of authorship. Readers and scholars of Wallace Stevens, William Carlos Williams, George Oppen, Frank O'Hara, Robert Duncan, Robert Creeley, Jerome Rothenberg, Susan Howe, Lyn Hejinian, Nathaniel Mackey, and Rae Armantrout will find much to learn and enjoy in this groundbreaking volume.
