‘Séamas Ó Catháin offers us a well-documented and engagingly illustrated account of the professional development of his predecessor, James Hamilton Delargy … Ó Catháin’s book productively highlights the crucial and extensive Scandinavian and northern European influences on Delargy’s work and, by extension, the importance of international perspectives in the early stages of the professionalization of Irish folklore studies', Ray Cashman, Journal of Folklore Research (March 2014).
