The Purdue Cooperative Extension Service is a part of the Land Grant University system through which efforts are made through non-formal and research activity to inform communities about their needs and engagement in agriculture and natural resources, health and human sciences, economic and community development, and 4-H youth. These historical documents cover topics in the aforementioned subjects, and date back to as early as the 1960s.
