Included are drafts, revisions, corrected copies and if published a copy of the reprint. Often there is material relating to the occasion on which the speech was delivered such as the invitation and program as well as correspondence and materials relating to Bowman's travel arrangements.

Bowman also kept a file of "Pertinent Remarks." These are typed and are at the end of this series.

There are also recordings of 4 speeches by Bowman. Bowman's speech to the MIT commencement on June 4, 1935 is recorded on 16 sides of a metal-based long playing record. His radio broadcast of February 24, 1941 to the Annual Conference of the National Association of School Administrators is on 2 sides of a metal-based record. "For this We Fight" broadcast on WEAF June 12, 1943 is on two glass records, one of which is broken. "The Hutzler Program" of April 2, 1946 on WBAL featured Bowman, and a copy of the LP is in the collection.

This series contains most but not all Bowman's speeches. Included are those for which manuscript material existed. Copies of speeches that were later published but for which there was no manuscript drafts are in the bound volumes of Bowman's collected writings in Series IV.
