In order to flesh out Zip and Mitzi Diamond, I read both The Rise and Fall of the Jewish Gangster in America by Albert Fried and Our Gang: Jewish Crime and the New York Jewish Community, 1900–1940 by Jenna Weissman Joselit. I also found a 1922 article from The Saturday Evening Post called “Inside the Bootleg,” which was helpful in understanding how a bootlegger might start his or her business.
