This subseries includes approximately 300 mostly high quality and visually compelling 8 x 10 inch glossy black and white prints, and eleven related contact sheets, of campus protest and activism between 1967 and 1970, many of which appear to have been made by Columbia University photographer Manny Warman. About half of the prints are of events on campus during the student strike in April and May of 1968, including daytime images of students standing on the ledges of Low Library, and of the occupation of the Mathematics building. A significant number of photographs document damage to buildings and evidence of their occupation by students. The subseries also contains photographs of campus protest and activism following the Spring 1968 strike, including SDS-led strikes and building occupations between March and May of 1969.
