The collection contains material generated by a variety of groups and offices on campus evidencing the varied activities undertaken by the Columbia community during this time of world crisis.

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.
