Series 1: International Labour Organisation Files, Subseries 3: Reports of Director-General (1949-1970) consists of lengthy reports on a variety of matters which Morse placed before the annual International Labour Conference, typically held in Geneva, and periodic regional conferences held in cities as far afield as Montevideo and New Delhi. The latter include the Conference of American States Members, the Asian Regional Conference, the European Regional Conference, and the African Regional Conference. Throughout Morse's tenure, the report of the Director-General, who serves as Secretary-General of the International Labour Conference and, frequently, of the regional conferences, played a central role in the deliberations of these assemblies. Heading, as they did, the agenda of each conference, Morse's reports were designed both to inform and animate debate, and to transcend a simple recitation of the ILO's activities by broaching issues of organizational, regional, and global importance. As Morse noted in his report to the International Labour Conference in 1951, "If these pages stimulate thought and discussion, if they help some to see more clearly than before the spirit which must inspire our work, if they encourage others to intensify their efforts to promote understanding between peoples and to improve the lot of their fellow men, they will have served their purpose."

Morse's reports to the regional conferences focused on phenomena of regional concern. Thus, in his report to the First African Regional Conference in 1960, "the year of Africa," he examined Africa's economic background, its patterns of employment, the education of its workers, and the field of action it presented to the ILO, both in terms of problems and solutions. Similarly, in his report to the Fifth Asian Regional Conference in 1962, he explored Asia's economic achievements and shortcomings as well as ways of surmounting the challenges posed by its developmental course, touching on everything from entrepreneurship and balance of payments to manpower planning and agrarian reform. In his reports to the International Labour Conference, Morse employed a larger canvas, offering broad socioeconomic overviews as well as discrete themes for discussion. He also provided an account of the ILO's activities in the preceding year. Among the topics he covered were productivity and welfare, workers' housing, automation and other technological developments, youth and work, labor relations, and the program and structure of the ILO. Morse's later reports are more voluminous, reflecting the introduction of a two-part format, one focusing on a particular issue and the other documenting the activities of the ILO.
