The Indiana University Modern Political Papers Collections consist of the congressional papers, photographs, audio-visual materials, and electronic records of Indiana's senators and members of the House of Representatives since World War II, and of prominent Indiana state legislators serving during the same period. Also included are complementary collections of materials from select former staff members, transcripts of oral history interviews, and a collection of campaign memorabilia.

The collections include the papers of senators Birch Bayh and Richard G. Lugar; the congressional papers of Lee H. Hamilton, as well as his post-congressional papers, papers from his co-chairmanship of the 9/11 Commission, the 9/11 Public Discourse Project, and the Iraq Study Group; the congressional papers of J.Edward Roush, Frank McCloskey, Dan Burton, and Mike Pence; the press files of Evan Bayh as both governor of Indiana and U.S. senator; the papers of Indiana senate president pro tempore Robert D. Garton; and the papers of former Birch Bayh staff members Jerry Udell and John Rector.

Online "finding aids," or guides to the collections, are either available through Archives Online at Indiana University or in process for all collections, some of which have been partially or fully digitized for online access. Photos from the collections may be accessed through Image Collections Online as the photo collections are developed.

Descriptions of each collection may be found in the Related Pages.
