 Whitman published his famous elegy to Abraham Lincoln in Sequel to Drum Taps, an 1865 pamphlet containing 18 poems about the American Civil War, as well as When Lilacs Last in the Dooryard Bloomed. Who said self-publishing doesn't work? Oh, captain, my captain, rise up and hear the bells. Rise up, for you the flag is flung, for you the bugle trills.
