Reading The Grapes of Wrath recently got me on a search for primary source documents from the Dust Bowl, and I found the Library of Congress’ Voices From the Dust Bowl site, which has a wealth of interesting news clippings, scrap books, and some really interesting newsletters written by migrant workers who lived in government migrant camps. The newsletters are full of funny pencil drawings, poems, gossip and jokes from the residents of the camps. There are even recipes!
These are just a small sample. Check out the newsletters yourself.
Also, read The Grapes of Wrath if you haven’t already. If you were forced to read it in high school, read it again! John Steinbeck captures the experience of the Dust Bowl with staggering eloquence and humanity. Outstanding and easily the best book I’ve read in a very long while.
