Unlike modern presidents, Theodore Roosevelt does not have a presidential library. Instead, his personal and presidential papers are scattered in libraries and other sites across the United States. The mission of the TR Center, based at Dickinson State University in North Dakota, has been to gather and digitize copies of all Roosevelt-related items to make his legacy more readily accessible to scholars and schoolchildren, enthusiasts and interested citizens. Items in the digital library include correspondence to and from Roosevelt, diary entries, notes, political cartoons, scrapbooks, newspaper columns, and magazine articles by and about Roosevelt, speeches, and photographs. Users can also view film clips and listen to audio recordings.
