Collections of American poet John Robinson Jeffers, who sets many of his works in California, include Tamar and Other Poems (1924). He knew the central coast and wrote mostly in classic narrative and epic form. Nevertheless, people today know also his short verse and consider him an symbol of the environmental movement. The Harry Ransom humanities research center at the University of Texas at Austin and the libraries at Occidental College, the University of California, and Yale University collect many manuscripts and materials of Jeffers. Survivors published a collection of his letters posthumously as The Selected Letters of Robinson Jeffers, 1887–1962 (1968). Jeffers wrote other books or criticism and poetry: are: Poetry, Gongorism, and a Thousand Years (1949), Themes in My Poems (1956), Robinson Jeffers: Selected Poems (1965), The Alpine Christ and Other Poems (1974), What Odd Expedients" and Other Poems (1981), and Rock and Hawk: A Selection of Shorter Poems by Robinson Jeffers (1987). Stanford University Press recently released a five-volume collection of the complete works of Robinson Jeffers. In an article titled, "A Black Sheep Joins the Fold", written upon the release of the collection in 2001, Stanford Magazine ably remarked that due to a number of circumstances, "there was never an authoritative, scholarly edition of California’s premier bard" until Stanford published the complete works. Biographical studies include George Sterling, Robinson Jeffers: The Man and the Artist (1926); Louis Adamic, Robinson Jeffers (1929); Melba Bennett, Robinson Jeffers and the Sea (1936) and The Stone Mason of Tor House (1966); Edith Greenan, Of Una Jeffers (1939); Mabel Dodge Luhan, Una and Robin (1976; written in 1933); Ward Ritchie, Jeffers: Some Recollections of Robinson Jeffers (1977); and James Karman, Robinson Jeffers: Poet of California (1987).
