Correspondence, manuscripts, documents, notes, photographs, and printed materials of James Lowry Clifford, 1901-1979, professor of English, Columbia University. Historical and literary letters and manuscripts collected by Clifford include letters from Samuel Johnson, diaries of Hester Lynch Salusbury Thrale Piozzi and those of her second husband, Gabriel Piozzi; a review of Clifford's book on Mrs. Piozzi and approximately nine drafts of one of Virginia Woolfs last typescripts.

The collection consists primarily of correspondence and subject files, but also includes manuscripts, documents, photographs and printed materials. The correspondence spans six decades and includes letters received by Prince Paul prior to his accession, during his tenure as regent, and during 35 years of exile. Correspondents include Prince Paul's family; European politicians, such as Edvard Beneš, Neville Chamberlain, Anthony Eden, and Benito Mussolini; European royalty, including King Albert of Belgium, King Carol II of Rumania, Queen Elizabeth II, King George VI, and King Edward VIII of England; Yugoslav public figures, such as Milan Stojadinoviʹc, Dragiša Cvetkoviʹc, and Anton Korošec. Subject files pertain to the reign of Prince Paul. These materials -- correspondence, minutes of meetings, military regulations, speeches, consular and foreign legation reports, police reports, voting records, government decrees, et cetera -- were assembled by J. B. Hoptner while researching his book, "Yugoslavia in Crisis, 1934-1941" (1962). Among the manuscripts are Prince Paul's and Princess Olga's diaries and Prince Paul's notes on conversations with Hermann Göring, Hitler, Mussolini, and Eden. Also included are historical documents concerning Serbian and Yugoslav history and the Karageorgevich family; documents from the 18th and 19th centuries, such as a copy of the 1808 agreement between Kara George and the Serbian National Council.
