His writings cover a number of fields. Among his more pretentious works are: "A Digest of All the Reported Cases... of Conn." (2 vols., 1871, 1882), "Cases on Railroad Law" (1896), "Modern Political Institutions" (1898), "American Railroad Law" (1904), "The American Judiciary" (1905), "The Relations of Education to Citizenship" (1912), "Life and Letters of Simeon Baldwin" (1919), "The Young Man and the Law" (1919). He was a most prolific writer of articles and pamphlets. Some ten years before his death he collected and presented to the Yale Law School nearly a hundred of these in four bound volumes which he entitled in order of numbering: Law and Law Reform, Studies in History, International and Constitutional Law, and Studies in Legal Education and Social Sciences. While these titles very aptly classify his literary output the volumes themselves do not contain all his miscellaneous publications.
