This fonds contains an initial section of articles and reviews written by J.M Hayden. The remainder is correspondence, notes, drafts, and research material relating to his Doctoral thesis, "The Estates General of 1614" and his four published books: "France and the Estates General of 1614", "The Manning of the British Navy During the Seven Years War" [written by Stephen Gradish and edited by Hayden], "So Much To Do, So Little Time: The Writings of Hilda Neatby" and "Seeking A Balance: The University of Saskatchewan 1907-1982." The latter two contain the most extensive material, and are particularly relevant to the study of the University of Saskatchewan's history.

This fonds contains annual reports, departmental correspondence, and exams.
