More than a century after his death, Walt Whitman remains a fresh phenomenon. Startling discoveries and massive transcription efforts are enabling new insights into his life and achievements. In the past few years new breakthroughs have proliferated, including the publication of a long-lost Whitman novel, Jack Engle, along with a hitherto unknown health guide for urban men and previously undiscovered poems. Myriad other documents have become more readily available, including largely unmined troves of journalism, narrative and documentary prose, and experimental note-keeping. Leaves of Grass and Whitman’s literary life as a whole are thus ripe for reconsideration. The Oxford Handbook of Walt Whitman embraces this expanded view of Whitman and charts new pathways in Whitman Studies by bringing in new perspectives, methods, and contexts.
