The American Whig-Cliosophic Society (1941-present) is a literary, political and debating society which has had an important impact on the lives of generations of Princeton students. It provides students with both social alternatives and an opportunity to develop skills not emphasized by the University curriculum. The contents of the initial group of records were acquired between 1941 and 1993 in agreements between Princeton University and the American Whig-Cliosophic Society. The library initially cataloged some of these records into the P Collection. Subsequently, an attempt was made to organize some of these records in 1975.
