Marie Runyon was an activist and former New York State legislator. Born in North Carolina in 1915, she moved to Morningside Heights and in 1963 began a decades long fight against Columbia University over its real estate practices and expansion in the neighborhood. Runyon founded the Morningside Tenants Committee as well as other tenants' organizations, and she brought a number of cases to court to prevent her eviction from her apartment at 130 Morningside Drive. She also worked for many political and service organizations throughout her career.

The Morningside Area Alliance is an organization working for community improvement on behalf of its member institutions in the Morningside Heights neighborhood in New York City. The organization was founded as Morningside Heights Inc. in 1947 through joint action of fourteen Morningside Institutions--Columbia University, St. Luke's Hospital, Cathedral Church of St. John the Divine, Teacher's College, Barnard College, Corpus Christi Church, Home for Old Men and Aged Couples, International House, Jewish Theological Seminary, Juilliard School of Music, St. Hilda's and St. Hugh's School, The Riverside Church, Union Theological Seminary, and the Women's Hospital of St. Luke's Center--with the expressed purpose of "[promoting] the improvement of Morningside Heights as an attractive, residential, educational, and cultural area." The collection includes much, if not all, of the material that was created by the organization as part of its daily business from 1947 to 1992, when the materials were accessioned into University Archives at Columbia University. This includes records of the Board of Directors and the various Committees within the Alliance; assorted publications, reports, pamphlets, and theses both acquired and created by the organization; files of the different offices within the organization; maps, plans, and photographs used and created by the Alliance for its work; and the collected materials and files created for the organization's projects in different subject areas--specifically buildings, community services and programs, public safety, schools, and the Morningside General Neighborhood Renewal Plan. The collection also includes a large quantity of material rearranged into subject files on different areas of concern within the organization.

The Richard Brick and Geri Ashur collection consists of materials related to film productions created and collected by Richard Brick and Geri Ashur, dating from 1968 to 2014. The materials document the career of Richard Brick as a filming professor, producer, and the first commissioner of the Mayor's Office of Film, Theatre and Broadcasting (MOFTB). The collection also includes materials related to films by Geri Ashur. The bulk of the collection focuses on the motion picture films and production files of the films Richard Brick and Geri Ashur produced, as well as the administrative records that document Richard Brick's contribution to the filming industry in New York during his tenure as the commissioner of the Mayor's Office of Film, Theatre and Broadcasting (MOFTB).

Beginning in the late 1970s, Columbia students urged the university to divest from companies doing business in South Africa in protest of South Africa's system of apartheid. After a series of student protests culminating in a month long blockade of Hamilton Hall in 1985, the Trustees voted to begin full divestment. The collection contains the administrative records of this decision making process in the 1970s-1980s.

The Strickman Cigarette Filter Collection documents Columbia's brief ownership of the patent for a cigarette filter invented by chemist Robert Strickman. Soon after their announcement of the agreement, the filter was found to be not much more effective than those in use at the time and Columbia withdrew its support. These records includes Columbia's statements, correspondence, and other materials generated throughout the incident.

Correspondence, speeches, reports, testimony, press releases, and articles of Young. The files document Young's leadership in many social welfare and civil rights organizations, as well as his activities as a columnist and speaker. Cataloged correspondents include Robert F. Kennedy, Lyndon B. Johnson, Hubert H. Humphrey, Martin Luther King, Jr., Coretta Scott King, Roy Wilkins, and John W. Gardner.

The files relate to his six years as chair of the CU History Department (1988-1994), plus a couple that refer to wider professional activities of some significance outside the University.
