The collection consists of printed materials issued by a large number of organizations, mainly student groups, although organized labour and women's groups are also represented in the collection. There is only a small amount of material for each organization, usually one file. The collection is supplemented by an uncatalogued pamphlet collection which also includes some international pamphlets. There are also a small number of button badges and some posters. Note: student organizations at McMaster University are part of the McMaster University fonds.
