Preface: The following outline is designed to assist students and teachers in the correlation of class lectures, discussions, and readings in courses on the history of American agriculture. It is a product of the needs of a course on the subject in the Graduate School of the United States Department of Agriculture, and it was used in a similar course in the department of history at the University of Missouri during the summer of 1933. As a bibliography, this compilation supplements but does not supersede the "Bibliography of the History of American Agriculture in the United States," prepared by Everett E. Edwards and issued as United States Department of Agriculture Miscellaneous Publication (Washington, United States Government Printing Office, 1939. 307 p.).
