O'Hara's analog photographs are mostly professional in content. They contain promotional photographs of O'Hara with her harp, events, including performances, and a small amount of candids of O'Hara, her husband Padraig O'Toole, and family. Materials are prints, except where slides are noted.

Collection is open for research.

Audiovisual recordings and born-digital content have been digitally copied from source media; all original media were retained, but may not be played due to format. Digital use copies can only be accessed in the Burns Library Reading Room. O'Hara's scrapbooks are closed due to fragility. Personal correspondence with Adrian Hastings and Deirdre Kelleher is restricted until 2025.
