The Roosevelt Institute for American Studies (RIAS) mission is to foster the study of American history in Europe, to facilitate research on the history of American politics, culture, and society, and to explore the historical development and trajectories of Dutch-American and, generally, transatlantic relations. The RIAS collections focus on a variety of issues such as civil rights, national security, intelligence, propaganda, radicalism, religion, and diplomacy. Collected over more than thirty years, these documents include presidential papers, personal correspondence and oral histories, departmental files, NGO records, diaries, memoires, historical periodicals, and journals.
