Today, 10 October 2018 marks the 90th anniversary of the foundation of the Irish Manuscripts Commission. This is the date on which the warrant of appointment, laying out the terms of reference for the Commission, was signed by W. T. Cosgrave, President of the Executive Council. IMC is still delivering on the core objectives captured in that warrant, to preserve and make available primary sources for the history of Ireland and thus to provide the documents on which the writing of history can be based.
