Autograph and typed letters from James Thomas Farrell to Schapiro, concerning Farrell's personal life, his writings, and current social and political affairs. There are also eight of Farrell's manuscripts from the 1960s. The long friendship of neighbors is seen in Farrell's personal letters about his private life and his family and in the discussions of whichever novel he was working on at the time. The main body of the correspondence is from the World War II period and shows much concern for current events in the Soviet Union as well as in the U.S. and Europe. The author also made a few forays into Irish humor, as in the use of his pseudonym, Jonathan Titelescu Fogarty. There are autograph drafts of Prof. Schapiro's replies to and notes about Farrell, and letters and post cards from Farrell's actress wife, Hortense Adler. Also, a letter from Frances Mitchell on her book, THE AWAKENING - LE REVEIL, 1950.

The subject files document Lazarsfeld's many research projects such as the Admissions Officers Project, 1964-1970, the Planning Project for Advanced Training in Social Research, 1950-1955, and his first major endeavor, the Princeton Radio Research Project, 1937-1940. There are complete records for his 1954-1955 study on McCarthyism's effect on college teaching.
