Much of the collection is made up of routine correspondence. There is, however, significant material documenting such ILGWU activities as the annual convention, Union Health Center, Unity House (the ILGWU resort), and Unity Broadcasting Corporation, which owned a number of radio stations across the country. In addition, the collection contains correspondence with government officials about labor situations in the garment industry during World War II, and information about health care, benefits, and pensions for workers. Some of Umhey's personal records are also included.

Significant individuals in the collection include Luigi Antonini, David Dubinsky, Morris Hillquit, and Meyer Perlstein. Among the notable organizations represented in the collection are the joint boards and local unions of the ILGWU, Labor League for Human Rights, Labor's League for Political Education, the Liberal Party of New York, the New York State School of Industrial and Labor Relations, and the U.S. Department of Labor.
