The collection contains materials relating to Olin and Emma Swenson, prominent activists in the fight for socialist causes in the Chippewa Falls, Wisconsin, area. Materials include newspaper clippings, letters from friends and family sharing their recollections of the Swensons, correspondence, photographs, a family history, and interviews. The material was gathered by a committee, the Friends of Olin and Emma Swenson, in an effort to write a book on the couple and their activities.
