The Michael O'Laughlin Collection was a gift of O'Laughlin in July 2020. It consists of book reviews, correspondence, presentation notes and research, Irish Roots Café website and podcast viewership statistics, summaries and outlines of future podcast episodes, song lyrics, publications, O’Lochlainns Personal Journal of Irish Families, photographs, sheet music, and audio and video that O’Laughlin created and collected related to Irish music, genealogy, and Kansas City and Midwest cultural life. The collection is particularly strong in sheet music, with over 150 titles dating from the late 1800s to mid-1900s.
