In the ten years since its publication by Four Courts Press in 2011 A dictionary of Irish saints has attracted a large amount of supplementary material, mainly through comments and corrections provided by readers, colleagues and reviewers. As these are to be included in a planned second edition of the Dictionary, it is felt by both Press and author that those who own a copy of the first edition should also benefit from them through this publication.

Scarcely a parish in Ireland is without one or more dedications to saints, in the form of churches in ruins, holy wells or other ecclesiastical monuments. Professor Pádraig Ó Riain's Dictionary of Irish Saints is intended to serve as a guide to the (mainly documentary) sources of information on the saints named in these dedications, for those who have an interest in them, scholarly or otherwise. The need for a summary biographical dictionary of Irish saints, containing information on such matters as feastdays, localisations, chronology, and genealogies, although stressed over sixty years ago by the eminent Jesuit and Bollandist scholar, Paul Grosjean, has never before been satisfied. Professor Ó Riain has been working in the field of Irish hagiography for upwards of forty years, and the material for the over 1,000 entries in his Dictionary has come from a variety of sources, including Lives of the saints, martyrologies, genealogies of the saints, shorter tracts on the saints (some of them accessible only in manuscripts), annals, annates, collections of folklore, Ordnance Survey letters, and other documents. Running to almost 700 pages, the body of the Dictionary is preceded by a Preface, List of Sources and Introduction, and is followed by comprehensive Indices of Parishes, Other Places (mainly townlands), Alternate (mainly Anglicised) Names, Subjects, and Feastdays. Professor Ó Riain's Dictionary has been described as 'an astonishingly comprehensive, intelligent and well-organized work'; it is unlikely to be superseded for many decades to come.

What was a mark? Livery of seisin? Letters patent? This remarkable Dictionary of Irish Local History will be able to tell you. Entries are fully cross-referenced and come replete with full biographical paraphernalia to enable readers to engage in further reading. Primarily intended for local historians, but the interconnectedness of the local and wider worlds is recognised by the inclusion of a range of entries relating to national institutions, religion, archaeology, education, land issues, lay associations and political movements. It is an indispensable work, which will enable local historians to make better sense of the evidence for the past.
