The President's office records of Charles W. Lyons, SJ, are composed of correspondence, memos, and writings documenting the fourteenth president's work. The bulk of the collection dates from 1914 to 1919, the dates of Lyons's presidency.

Correspondents include Father Provincial Joseph Zwinge; lawyer Edward A. McLaughlin; and the New York State Department of Education, which approved the Bachelor of Arts, Bachelor of Sciences, and Bachelor of Philosophy degrees. Several folders contain correspondence related to the construction of St. Mary's Hall, primarily from architecture firm Maginnis & Walsh. One letter by Sister Mary Edmond from 1979 contains remembrances of Boston College High School and Lyons.

The student military training records are split into two groups: the Student Army Training Corps (SATC) operated during wartime, while the Army Reserve Officers' Training Corps was established after the 1918 armistice. Materials in both subseries consist of memos, forms, training manuals, course and class lists, and other related material. Also included are pages of student publication Stylus, which contain published photographs. Many of the memos in these subseries were sent to or from the United States War Department, a precursor to the Department of the Army. The writings series is made up of an article about "home night," a precursor to homecoming, two printed copies of a Fourth of July oration by Lyons, and a typescript of his obituary, written in Latin.
