This work is designed to show a double influence: first, that of American poets, especially Whitman, on W. B. Yeats, and, second, of Yeats on a wide range of American poets who began their careers during the first decades of the century. Originally published in 1983. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
