With the exception of letters to John Dewey, George Rives, G. Stanley Hall and some original incoming correspondence, the papers of James McKeen Cattell consist of typescript copies of correspondence with Seth Low, Nicholas Murray Butler, and faculty members, dealing with Psychology Dept. matters, professional matters, and Cattell's battle for academic freedom which ended in his dismissal from and subsequent suit against Columbia. Included are typescript copies of University reports, printed court records, and transcripts of correspondence with Cattell's lawyers.
