"I ain't a writer," Woody Guthrie once wrote, "I want that understood. I'm just a little one-cylinder guitar picker." Of course, that humble sentiment was part of his public persona--the howdy-doo Woody Guthrie, the ramblin' everyman, the down-home folk singer, poet of the people. The truth, however, is that Guthrie wrote an incredible amount of material: songs, essays, poems, stories, diaries, and letters. In total, an estimated 750,000 words were left unpublished when Guthrie died in 1967.
