University College Dublin has put its history archive collection online. There is a lot in here of interest to historians and anyone interested in Irish history. The collection includes visual images as well as paper archives. The link below is to the site. It seems to be readily searchable and easy to use. Happy to add this to Politicalworld.org's growing collection of links to Irish history digital archives.
