Walter Muir Whitehill, in his study Independent Historical Societies (Boston Athenæum, 1962), praised the Maine Historical Society as the most “productive of publications” of all New England historical societies during the nineteenth century. The Society produced twenty-six volumes of Collections between 1831 and 1900, eleven volumes of York Deeds between 1887 and 1896, and another twenty volumes of Collections between 1901 and 1916 — an impressive output by any standard. These many volumes, with their wealth of narrative and documentary history, are a rich resource for scholars and laymen alike.
