Abstract: Papers primarily on a two-year study, 1946-1948, proposed and conducted by Professor Edmund I. Zawacki of the Department of Slavic Languages, University of Wisconsin, which aimed at taking a microscopic look at a Polish-derived community in Wisconsin, measuring how both the culture of the Polish immigrant and the culture of the American inhabitant were changed as a result of heavy Polish immigration into the area. The collection consists of correspondence; research material obtained from a year's field work by Harriet Pawlowski in Independence, Wisconsin, including eighty case histories of Polish families in the area; various explanations and summaries of the study; an outline and chapter drafts for the projected but never completed study report; photographs, and sound recordings. Also present in paper form only are several articles and lectures, 1953-1957, by Zawacki on U.S. international relations and the Cold War, as well as materials, 1935-1993, focusing on Zawacki's interest in international relations, the Cold War, and sister cities.
