The materials that comprise the Historical Biographical Files have been collected and added to from a variety of sources over the years by current and previous staff. The files consist of materials related to people who have a connection to the University whether as student, alumni, administrator, faculty, staff, guest lecturer, or honorary degree recipient. Materials generally consist of newspaper and magazine clippings, press releases, programs, ephemera, printed matter, lists, reports, and pamphlets.

This collection contains copies of Butler's speeches delivered at Columbia University as well as at numerous other institutions from 1882 to 1947 during his tenure as president of the Industrial Education Association as well as Columbia University. While the speeches address a number of topics, they primarily focus on the state of America's higher educational system, potential educational reforms, and local and international American politics (particularly in relation to the Republican Party and war).
