This is a collection of personal papers belonging to John Concannon, a New York City-area journalist and member of the Ancient Order of Hibernians and other Irish-American organizations. These papers document both his personal and professional activities and his involvement with a variety of Irish-American organizations, especially the Ancient Order of Hibernians. The nature of these materials is related to Concannon's role as a member or officer of these organizations, or as research done in the service of his writing projects.

The collection includes a significant number of papers related to the Ancient Order of Hibernians at the national, state, county, and division level, with an emphasis on the St. Patrick's Day Parade, National Board, and New York divisions. Note that these are not necessarily official records kept by the AOH, but rather documents created or received by John Concannon in his various member and officer roles. The collection also includes many papers belonging to James Comerford, who served as AOH National President from 1962-1964, New York City St. Patrick’s Day Parade Chairman from 1965-1984, and Editor of the National Hibernian Digest from 1958-1962, 1970-1972.

A wide range of Irish-American organizations are represented in the collection, with an emphasis on the Galway Men's Social and Benevolent Association, United Irish Counties Association, and the Society of Friendly Sons of St. Patrick.

Materials are largely textual, comprising correspondence, clippings, publications, internal reports, event programs, articles, press releases, and notes. A smaller number of materials are in the format of photographs, videocassettes, and audio recordings.
