the Division of Public Records of the Pennsylvania Historical and
Museum Commission, are invaluable for the study of opposition to
the Constitution outside Philadelphia. The William Irvine Papers
in the Historical Society of Pennsylvania contain important letters
concerning the opposition, especially in Cumberland County. Other
valuable collections in the Historical Society of Pennsylvania are
those of such supporters of the Constitution as Tench Coxe, Levi
Hollingsworth, and James Wilson. The Pemberton Papers contain
material on Quaker opposition to the slave-trade clause of the Con-
stitution.
The Library Company of Philadelphia has the papers of Benjamin
Rush; and the papers of Robert Aitken, a Philadelphia printer and
bookseller, which contain information on the dissemination of Anti-
federalist literature. The Robert R. Logan Collection of John Dickin-
son Papers contains letters concerning Dickinson's publication of the
"Letters of Fabius." The library of the Independence National His-
torical Park has Jasper Yeates's notes of debates in the state Convention.
Several libraries and a private collector outside Pennsylvania have
useful material. The Manuscript Division of the Library of Congress
has the Shippen Family Papers, which include letters of William
Shippen, Jr., a Philadelphia Antifederalist who was married to the
sister of Richard. Henry Lee of Virginia. The Rare Book Room has
a large collection of pamphlets and broadsides. The William L.
Clements Library at the University of Michigan and H. Bartholomew
Cox of Washington, D.C., each own a part of Anthony Wayne's notes
of debates in the state Convention. The Timothy Pickering Papers
in the Massachusetts Historical Society contain information on
Pickering's support of the Constitution and on attitudes toward the
Constitution in Luzerne County.
Newspapers and Magazines
The most important sources for the history of the debate over the
Constitution in Pennsylvania are the fifteen newspapers and two
magazines that were published in the state at one time or another
between September 1787 and June 1788. Ten of the newspapers and
the two magazines were published in Philadelphia. The Philadelphia
newspapers appeared daily, semiweekly, triweekly, and weekly.
The Philadelphia dailies were Eleazer Oswald's The Independent
Gazetteer; or, the Chronicle of Freedom and John Dunlap and David
C. Claypoole's The Pennsylvania Packet, and Daily Advertiser. The
Packet, a Federalist newspaper, contained little original material
about the Constitution. Oswald printed both Federalist and Anti-
federalist pieces in the Gazetteer until mid-November. Thereafter
