The Mellon Centre for Migration Studies is a dedicated resource and research Centre with specialist expertise in the universal phenomenon of human migration. Our understanding of migration is holistic and encompasses immigration, internal migration and emigration. With regard to the latter we are focussed upon the peoples of the island of Ireland and their distribution across the globe. The Centre is located at the Ulster-American Folk Park, outside Omagh, County Tyrone, which is part of the National Museums NI. The Centre houses a specialist reference library in partnership with Libraries NI. The collection extends to over 18,000 items. Our main digital resource is the Irish Emigration Database which is operated in conjunction with Queen’s University Belfast at dippam.ac.uk.
