The papers consist of correspondence, course materials, diaries, legal documents, printed material, reports, subject files, and writings that document Underhill Moore's career as an academic and his personal life. The Correspondence Series is the most voluminous and contains large amounts of intermixed professional and personal correspondence and related materials. The Personal and Family Papers focus upon the Moore Family and the strong role that Moore played in lives of his children and extended family. The voluminous and detailed nature of the papers which span fifty years provide substantial evidence of Moore's evolving roles as law student, practicing attorney, and law professor in his professional life and as an ardent suitor, husband, and father in his personal life.
Moore's writings are highlighted by Law and Learning Theory: A Study in Legal Control, which represents the culmination of a decade's study by Moore and his colleague Charles C. Callahan at the Institute of Human Relations at Yale University of the effect of automobile parking law enforcement upon driver behavior. Although the collection does not contain any preliminary data developed during the study, there are two different drafts of the book in the Writings Series.
The Underhill Moore Papers were processed as part of a collaborative effort between Manuscripts and Archives and the Yale Law School to document the careers and accomplishments of law school faculty and alumni.
