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.
Anti-Federalist Papers
Until the mid-20th century, there was no united series of anti-Federalist papers. The first major collection was compiled by Morton Borden, a professor at Columbia University, in 1965. He "collected 85 of the most significant papers and arranged them in an order closely resembling that of the 85 Federalist Papers". The most frequently cited contemporary collection, The Complete Anti-Federalist, was compiled by Herbert Storing and Murray Dry of the University of Chicago. At seven volumes and including many pamphlets and other materials not previously published in a collection, this work is considered, by many, to be the authoritative compendium on the publications.
