Murphy, Francis, ed. Walt Whitman: A Critical Anthology. Baltimore, Md.: Penguin Books, 1969, 482 pp. Fifty-five items are reprinted here, nine of them by Whitman himself. The materials (many of which are excerpts) range from Emerson's famous 1855 letter to Louis Simpson's 1965 poem, "Walt Whitman at Bear Mountain." The selections are arranged under three headings: "Contemporaneous Criticism," "The Developing Debate," and "Modern Views." The editor has chosen discussions and analyses which "encourage the widest possible range of opinion, critical viewpoint and method."
