In this Series, material is divided by district, committee, and regional as well as by topic and format. While a portion of this Series is printed and public, including district and national bulletins, fliers, journals, and pamphlets, the majority consists of internal documents. Folders contain drafts and memos on such pertinent topics as, agitation and propaganda relating to the development of a organizational newspaper, the black national question, busing in Boston, Cook County Hospital, the equal rights amendment, fusion between the workers movement and the social movement, the international situation mostly pertaining to the situation in China following the death of Mao Tsetung and the Three Worlds Theory, the national question, and the woman question.

Folders outlining the RWH's political campaigns surrounding African Liberation Day and May Day contain fliers and reports. Central to this Series is the RWH's work with uniting Marxist-Leninists in the United States. There are folders outlining lengthy merger discussions with the Bay Area Communist Union, the Communist Party (Marxist-Leninist), the Committee to Unite Marxist Leninists, and the League of Revolutionary Struggle. At times discussions lasted over the course of several years. Heavily important to the RWH was its work in trade unions and the trade union movement. There is a sizable amount of material in this Series, which outlines various trade union strategies and involvement in the auto, electrical, mining, and steel industries.

Series IV contains material generated by the Communist Party (Marxist-Leninist) (CPML), which dates from 1976 when the organization changed its name from the October League up through 1981. While there are public and printed documents in this Series in the way of district and national bulletins and pamphlets from The Call and Call Publications, most of the material is internal. A large portion of this Series is made up of reports from various districts and regionals. These consist of page long, occasionally hand-written briefs outlining political campaigns and recruitment work going on in the CPML's districts and regionals around the country. Another sizable portion of this Series consists of notebooks filled with minutes and notes from meetings of the Political Bureau and the Standing Committee.

Like Series III, there is material related to various merger negotiations amongst U.S. Marxist-Leninist organizations, including the Revolutionary Workers Headquarters and the New Voice.

Series V contains material related to the union organizing work of David Sullivan. It is presumed that these materials relate to work he himself engaged with, but there could also be material related to work he simply collected on. The Series is broken down by union, first the United Autoworkers and then the United Steelworkers of America. This Series highlights the activities of rank and file activists within these two unions and their various locals. Material from the United Autoworkers largely comes from the ALCOA plant in Cleveland and includes a folder of grievances that Sullivan filed with the union. There are numerous locals represented from the United Steelworkers of America, most with small runs of bulletins and newsletters from rank and file activists within the local. These include Local 1014's Coke Plant Breeze and the Mill Hunk Herald. Political fliers and brochures related to the campaign of James Balanoff for President of District 31 are found in this Series as well as material related to other union election campaigns.

Series VI consists of files of material identified by subject. These files contain clippings, minutes and notes from meetings, pamphlets, and other publications related to the topic at hand. The handwritten minutes and notes within these files suggest that the creator of them was involved with the organizations represented, such as the National Lawyers Guild and the Vietnam Veterans Against the War. The other major subject represented in the files is related to women's rights generally, abortion and the equal rights amendment more specifically. Of particular note, this Series contains material related to a fundraising effort of David Sullivan, whereby he was selling the poetry of influential communist Leibel Bergman in order to raise money for Bergman's bills. Volumes of Bergman's poetry can be found here, as well as a part of his FBI file.

Series VII makes up the largest portion of the collection and contains folders of material documenting the printed and public matter produced by hundreds of U.S. leftist organizations. Contained within the files are brochures, fliers, pamphlets, and other publications. A majority of the organizations were affiliated with the U.S. Marxist-Leninist-Maoist tradition, such as the August 29th Movement, the Bay Area Communist Union, the Black Workers Congress, Freedom Road Socialist Organization, and the October League.
