Collection of campaign materials spans most of the United States political timeline, from 1840 to 2009. National and state political campaigns run by the Whig, Know-Nothing, Democratic, Republican, Libertarian, Greenback, Independent, Citizens, and other parties, are documented through printed material, artifacts, and ephemera, such as posters, flyers, buttons, bumper stickers, party platforms, texts of speeches, pamphlets, newspapers, and clippings. Many of the items related to national party conventions. Materials from state campaigns and other elections such as mayoral races chiefly come from North Carolina, with smaller amounts from Louisiana, Maryland, Massachusetts, and other states. There are some materials documenting 20th century Durham, North Carolina political history, as well as a few items pertaining to a Humphrey-Muskie Committee at Duke University. Other political organizations and caucuses are also represented, including anti-war organizations, labor unions (especially the AFL-CIO), and various other citizens' groups such as the NAACP. The collection is divided into four series: National Elections, America Votes (materials from a 1996 exhibit of campaign memorabilia at Duke), State Elections, and Political Campaign Memorabilia. Each series is arranged by election year, with a few exceptions, and within, alphabetically by party, state, or topic. There is also a group of oversize materials separated from the main collection, chiefly newspapers and posters.
