The collection consists of research material created or collected by Olof Seaholm pertaining to Swedish immigration and organizations to Canada and North America. The collection mainly consists of general research material related to these themes, but there is some more specialized research into specific areas of Swedish Canadian history, such as the Scandinavian Central Committee and the International Order of Good Templars. Textual records in this collection include minute books, clippings, a constitution, correspondence, research notes, newspaper and magazine issues and clippings, books, and photographs documenting Swedish communities in British Columbia and research material about Swedish activities in North America.

The collection contains four series related to Seaholm's research. They include the Swedish Canadian research material series; Scandinavian Central Committee series; Independent Order of Good Templars series; and the Swedish Canadian Rest Home material series.
