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.
The Independent Journal
By January 8, 1788, thirty-six Federalist essays had been published between the newspapers. John McLean bundled these thirty-six together and published them as "The Federalist: A Collection of Essays, Written in Favour of the New Constitution, as Agreed upon by the Federal Convention, September 17, 1787", Volume I, on March 22, 1788. Publication of the essays resumed on 11 January, and essays thirty-seven to seventy-seven were published from that time through to April 2, 1788. Before the final eight could be published publicly in the newspapers, John McLean compiled and released Volume II of "The Federalist" essays, which consisted of essays thirty-seven through eighty-five, on May 28, 1788. The eight unpublished essays appeared in "The Independent Journal" and "New York Packet" between June 14 and August 16.
