The Federalist Papers
The Federalist (later known as The Federalist Papers) is a collection of 85 articles and essays written by Alexander Hamilton, James Madison, and John Jay under the pseudonym "Publius" to promote the ratification of the United States Constitution. The first 77 of these essays were published serially in the "Independent Journal", the "New York Packet", and "The Daily Advertiser" between October 1787 and April 1788. A two-volume compilation of these 77 essays and eight others was published as The Federalist: A Collection of Essays, Written in Favour of the New Constitution, as Agreed upon by the Federal Convention, September 17, 1787 by publishing firm J. & A. McLean in March and May 1788. The collection was commonly known as "The Federalist" until the name "The Federalist Papers" emerged in the 20th century.
The Complete Anti-Federalist
This is meant to be an authoritative edition. It includes all Anti-Federalist pamphlets that I have been able to find, all substantial newspaper essays and series of essays, some of the most important speeches by Anti-Federalists in ratifying conventions (though there is no claim of or need for comprehensiveness here), and some manuscript notes. About two-thirds of the items have never been printed since their original publication in 1787 and 1788, including a number of pieces that are of major importance in the Anti-Federal corpus... I have, of course, given a good deal of thought to the great length of this collection, though it was always understood that it would be more than one volume. I would have preferred it shorter; but there is, I think, no way to accomplish that that does not strike at the heart of the basic conception of this enterprise from the beginning: that all of the substantial Anti-Federalists pieces should be made available in their entirety and in an accurate text. Some of the most important series of essays, such as Centinel, and the Letters from the Federal Farmer, and Brutus, and A [Maryland] Federal Farmer, are very long. There is no possibility of omitting these or of abridging them without destroying a prime value of the collection.
