The recently released 1964 interviews of Jacqueline Kennedy by Arthur Schlesinger Jr. make for fascinating reading. But if the one subject on which I have some detailed knowledge is any indication, historians will need to be careful about putting too much stock in what Mrs. Kennedy said.

The subject is President John F. Kennedy's writing partnership with Theodore Sorensen, his close aide and White House special counsel, once referred to by JFK as his "intellectual blood bank."

Mrs. Kennedy portrays her husband as the principal author of his Pulitzer Prize-winning book, "Profiles in Courage," as well as his inaugural address.
