Correspondence, 1908-1949 (Microfilm rolls 1-91, Manuscript boxes 1-47). The series has been arranged chronologically, with undated letters placed at the end of the relevant month, year, or decade, depending on which is apparent, or at the very end of the series, if no date is apparent. Other undated letters have been categorized by periods of Murphy's life (e.g., Detroit period, gubernatorial period, etc.) and placed at the end of the period.
