The records of DE/2 were part of the holdings of the State Paper Office, Dublin Castle to which they were transferred from the Library of Dáil Éireann in the 1960s. They consist of administrative files of the Dáil Éireann Secretariat. The files contain original and copy correspondence, primarily between Diarmuid Ó hÉigeartaigh, Secretary to Dáil Éireann, and members of the Dáil Éireann cabinet, as well as members of the Dáil. The files contain documents generated by the functioning of the administrative apparatus established in the aftermath of the 1918 general election to support the activities of the Dáil Éireann government. They include files relating to the Treaty negotiations.
