Series II: Individuals, 1879-2010 consists of materials collected by Dr. Moloney throughout the course of his academic and professional activities concerning specific individuals and groups. The majority of these individuals and groups are Irish or Irish-American, are closely associated with Irish traditional music, and often performers. Others are Irish or Irish-American academics, poets, and writers, including the Philadelphia-based historian Dennis Clark. Of particular note are materials related to Dr. Moloney himself that provide an insight into his private and public lives. Included in this series is a small set of materials given to Dr. Moloney by fiddler and radio host Tommy Caulfield, including ledger books, correspondence, radio receipts, advertisements, and concert programs which provide documentation on the Irish Musicians' Association and the Irish Musicians' Union in Philadelphia beginning in the 1940s.
