An indispensable work of reference for scholars, journalists, broadcasters, genealogists, diplomats, and the general reader interested in Ireland’s past or in biography, it is an educational resource of huge potential.

The Dictionary of Irish Biography outlines the lives at home and overseas of prominent men and women born in Ireland, north and south, and the noteworthy Irish careers of those born outside Ireland. Biographies range in length from 100 words to 15,000. 

The chronological scope of the Dictionary extends from the earliest times to the twenty-first century. The living are not included. The online edition is updated twice yearly. Revisions and corrections are undertaken biannually.
