I'm very happy to announce the launch of the new Irish History Online website (www.iho.ie). Irish History Online (IHO) is a bibliographic catalogue comprised of publications written about Irish history from earliest times to the present. The IHO catalogue lists works on Irish history published since the 1930s, with selected material published in earlier decades. With over 116,000 entries, it's not easy to make a rich dataset like this navigable, but hopefully a lot of new functionality and an array of visualisations will open it up to every user. It was brilliant to work with the wonderful staff at the Royal Irish Academy to make this happen. Explore this exciting resource at www.iho.ie
