<human>:  I am writing an article on the Great Depression era and am looking for additional sources. Can you recommend any books or other primary sources I should look into?
<bot>: Some books you could look into to help with your research include: "The Worst Hard Time: The Untold Story of Those Who Survived the Great Depression" by Timothy Egan, "The Forgotten Man: A New History of the Great Depression" by Amity Shlaes, and "The Great Depression: America, 1929-1941" by Robert S. McElvaine. You may also want to look into newspapers or other primary sources from the era to learn more about the impact of the Great Depression.
