Original meaning
Originalists of all stripes cite "The Federalist Papers". It is fairly tenuous to suggest that this represents a good source for the original "intent": after all, Alexander Hamilton, who wrote the majority of those essays, was absent for the greater part of the Philadelphia Convention, and John Jay did not attend it at all. However, James Madison, the principal framer of the Constitution also wrote a substantial amount of "The Federalist Papers". Also, to suggest Hamilton and Jay's absence from the convention implies their ignorance as to the Constitution's original meaning is demeaning to those two men and inaccurate. The collected anti-Federalist papers, of course, will be no use at all to a person searching for the original "intent" of the framers. However, as evidence of how a reasonable person at the time would have understood the words of the Constitution, "The Federalist Papers" and the anti-Federalist essays are evidence of direct relevance.
John Fenno
Jefferson and his colleagues, angry at Fenno's attempt "to make way for a king, lords, and Commons" set up rival newspapers, the "Aurora" edited by Benjamin F. Bache and the "National Gazette" edited by Philip Freneau, to promote the newly formed Democratic-Republican Party. As a highly visible Federalist spokesman, Fenno was engaged in verbal disputes that once led to fisticuffs with Bache. The tone of the "Gazette of the United States" was somewhat above the average of its contemporaries, and the Federalists were well served through its columns, although the circulation never exceeded 1,400. Copies circulated to major cities where other Federalist newspapers freely copied the news and editorials.
