Historians have raised eyebrows at the footnotes in the new book about Thomas Jefferson, “Master of the Mountain.” In particular, they point to the author’s treatment of the work of another writer, whose transcriptions he calls “erroneous and misleading.” David Waldstreicher, a historian at Temple, called those footnotes “fighting words.” A professional historian, he continued, “would publish this in a scholarly journal and make it very clear how it makes a difference, instead of using it to say, ‘I am the last word.’”
