ILHOP is a forty-year-old oral history project focused on Iowa workers and their unions. It was founded by the Iowa Federation of Labor (IFL) and is now a joint project of the IFL (AFL-CIO), the University of Iowa Labor Center, UI Libraries, and the State Historical Society of Iowa. With memories spanning the period between the 1890s to the present, ILHOP's over 1,200 oral history interviews touch
on a range of subjects related to social, labor, and working-class history, including dozens of industries and unions, the Great Depression, World War II, deindustrialization, African American civil rights, women's rights, and the struggles of recent immigrants and refugees.
