Irish Historical Studies, the joint journal of the Irish Historical Society and the Ulster Society for Irish Historical Studies, is published twice yearly (May and November). Established in 1938 under the editorship of T.W. Moody and R. D. Edwards, it publishes (besides articles) select documents, with editorial comment, and lists of theses completed. I.H.S. pioneered the publication of annual lists of writings on Irish history, lists that form the basis for the fully searchable and regularly updated database Irish History Online (www.irishhistoryonline.ie), established in 2003.
