PBS offered a five-part series on the 1930s era. Episodes included "The Crash of 1929," "The Civilian Conservation Corps," "Hoover Dam," "Surviving the Dust Bowl," and "Seabisquit." The American Experience programs draw parallels between the 1930s and current political climate and include available online resources.
Another resource on the 1930s with a specific focus on the Dust Bowl is Rain: A Dust Bowl Story. The site includes an epic story of a young American farm family struggling through the hard times of the Depression Dust Bowl. New mini-episodes appear daily.
