The collection consists of the papers of Jamie G. Partridge, an activist from Portland, Oregon. The bulk of the collection reflects Partridge's involvement with labor, social justice, and socialist causes and organizations. These include administrative records, flyers, newsletters, bulletins, correspondence, and Partridge's handwritten notes for organizations including the Portland chapter of the Democratic Socialists of America, Communities and Postal Workers United (CPWU), the National Association of Letter Carriers (NALC) Branch 82, Portland Jobs with Justice, and the International Socialist Organization (ISO). A significant portion of the International Socialist Organization records consists of bulletins and articles from the Socialist Worker with handwritten annotations by Partridge.

Other organizations and causes represented in the collection include multiple organizations based at Portland State University that Partridge was involved with; Labor Radio on KBOO, which Partridge programmed; the Portland Labor Committee on Central America and the Caribbean; and the gay liberation movement. The collection also includes issues of Rainbow News, a newspaper for the Oregon Rainbow Coalition that Partridge edited, and photographs taken for Rainbow News. Personal papers in the collection include writings by Partridge; articles and other materials referencing Partridge; photographs; and a scrapbook of photographs, clippings, correspondence, and ephemera from the 1950s through the 1970s.
