Consider other works by Steinbeck, such as Of Mice and Men, Cannery Row, and East of Eden.
Consider nonfiction works that illuminate the Great Depression and the changes it brought to America, such as Studs Terkel's Hard Times, Timothy Egan's The Worst Hard Time, and Amity Shlaes's The Forgotten Man.
Consider more contemporary fiction that reflects on the Great Depression, such as Water for Elephants by Sara Gruen and Fried Green Tomatoes at the Whistle Stop Café by Fannie Flagg.
