Abstract: This is a collection of six bound volumes of Irish newspapers and ephemera covering the period 1916 to 1940. The majority of the material in four of the six volumes is from the Civil War period, 1922-23. These four volumes include long runs of anti-treaty newspapers including the Daily Sheet, the Daily Bulletin and Poblacht na h-Eireann and issues of other titles such as The Fenian and The Flame. In addition, there are many anti-treaty ephemeral items such as leaflets and short pamphlets. Bound in with these Civil War materials are occasional items from 1916, the War of Independence and the early years of the Free State. In addition to the four volumes pertaining to the Civil War era, one of the volumes contains a weekly newspaper entitled Nationality, edited by Arthur Griffith, covering the period September 1917 to February 1919 and another volume includes issues of the Republican Newspaper War News from the period 1939-40.
