Either late this year, or early next year, I will step into the waters of early-modern Irish history. My primary focus will be James Ussher and his interpretation of patristic history. A friend of mine, Tom Powers, suggested a number of good books to look at – namely those by Ciaran Brady, Steven Ellis and Nicholas Canny – and what looks to be an indispensable website. The Irish History Online website is a database that records the bibliographic information for any book or article on this subject. This coupled with the Ussher Project website will put me in good stead.
