The Tamiment Library and Robert F. Wagner Labor Archives Printed Ephemera Collection on the Socialist Workers Party (SWP) consists of constitutions, convention proceedings, reports, memoranda and press releases as well as printed ephemera such as fliers, brochures, circular letters, newspapers clippings, pamphlets and publications.

Series I: Socialist Workers Party General Files, 1937-1996, contains printed material put out by the Socialist Workers Party, including fliers, brochures, conference announcements, pamphlets and publications. Also included are constitutions, memoranda, press releases and convention proceedings. A large portion of this Series is material related to SWP national and local election campaigns, ranging in date from George Breitman's campaigns in the 1940s for City Commission in Newark and US Senator of New Jersey up through various national and local campaigns in 1992. There are materials put out by youth groups in the 1960s and 1970s in support of SWP candidates including Young Socialists for Halstead and Boutelle, High School Students for Boutelle, and the Young Socialists for Jenness and Pulley. This Series also contains a number of fliers for events and meetings. When noted, material has been separated by department or committee, with material coming largely from the National Education Department and consisting of course outlines and discussion guides on the history of Bolshevism, Trotskyism, the ABCs of Marxism, and dialectical materialism. This Series contains two scrapbooks, collections of articles and fliers on the "Negro Question" and the "Russian Questions." A large selection of the material was generated by the SWP nationally, relating to events, meetings, and conferences happening in and around New York State and City. However, there are a few files documenting events from other locations around the US, including Los Angeles, Minnesota and New Jersey.

Series II: Socialist Workers Party Affiliated and Youth Organizations, 1932-1999, contains printed material put out by various groups affiliated with the Socialist Workers Party, including their youth wing known as the Young Socialist Alliance (YSA). Included from the YSA are event fliers outlining the YSA's opposition to the Vietnam War, their position on black nationalism and feminism, and their support for labor and unionization generally, as well as for a 1970 strike of cafeteria and library workers at NYU. From YSA there are also election campaign materials, stickers, conference brochures, educational bulletins, and a number of pamphlets and brochures describing who the YSA are and how to join. Series II also contains material from the Communist League of America (Opposition), a predecessor of the SWP, the International Tendency, a break away group, and a wide selection of event fliers held at the Militant Labor Forum.

Series III: Presses and Publishers, 1934-1998, contains pamphlets and publications put out by the presses and publishing houses affiliated with the Socialist Workers Party. These include, Merit Publishers, Pathfinder Press, and Pioneer Publishers, as well as material by the SWP's own newspaper, The Militant. The pamphlets are organized by date as well as by subject. Prominent topics in the collection include: African Americans and civil rights, feminism and women's liberation, Cuba, fascism, labor and the Labor Party, McCarthyism, and the Minneapolis Trial where 18 leaders of the Socialist Workers Party and Minneapolis Truckdrivers Union were convicted and imprisoned.
