The Irish English Resource Centre is a website developed and maintained by Raymond Hickey, Professor in Linguistics at the University of Duisburg and Essen, a renowned expert on the variety of English spoken in Ireland. The website aims to ‘make material on the historical and regional diversity of Irish English, in the north and south of the country, and information on the sociolinguistics of present-day varieties, available to the interested public’. The contents are divided into twelve sections, which can be accessed in different ways: (i) Introduction, (ii) Levels, (iii) Urban varieties, (iv) Ulster, (v) Surveys and data, (vi) Transportation, (vii) Wider context, (viii) Search, (ix) Links, (x) Research, (xi) References, and (xii) Maps.
