The Quinn collection was gathered by Herbert Furlong Quinn between the 1930s and 1970s to support his research of political sciences.
The collection mainly presents a dozen Canadian political parties as well as several foreign parties using brochures and political newspapers covering the period from the 1930s to the early 1980s. The Canadian political parties represented are the Parti libéral du Québec, the Liberal Party of Canada, the New Democratic Party, the Progressive Labor Union, the Commonwealth Co-operative Federation, the Progressive Conservative Party, the Confederation of Catholic Workers in Canada, the National Union, the Social Credit Party of Canada, the Bloc Populaire, the Canadian Student Assembly, among others.
