If I read this [sub required] correctly, David Kirkpatrick of the New York Times has already seen them and there seems to be nothing there:
Mr. Morgan’s memorandum and other records of Concerned Alumni are contained at the Library of Congress in the papers of William A. Rusher, a leader of the group and a former publisher of National Review.
Those records and others at Mudd Library at Princeton give no indication that Judge Alito, who sits on the United States Court of Appeals for the Third Circuit, was among the group’s major donors. He was not an active leader of the group, and two of his classmates who were involved and Mr. Rusher said they did not remember his playing a role.
