I am starting a community-engaged research project on Latino railroad workers on the Midwest. This is a project that we at the University of Nebraska at Omaha's Office of Latino/Latin American Studies are doing with/for the Union Pacific Railroad Museum. Our objective is to collect between 20 and 25 oral histories with former railroad workers from the Midwest/Great Plains regardless of whether they worked for Union Pacific or not. We have found extraordinarily little bibliography on this topic. Can anyone point us to some resources?
