The Dublin Metropolitan Police (DMP) Prisoners Books for 1905-1908 and 1911-1918 are amongst the most valuable new documents to come to light on the revolutionary decade. They include important information on social and political life in the capital during the last years of the Union, from the period of widespread anticipation of Home Rule, to the advent of the 1913 Lockout, the outbreak of the First World War, the Easter Rising and its aftermath, including the conscription crisis of 1918. They will also be invaluable to those interested in criminology, genealogy, and family history.

This collection comprises the papers and correspondence of the Kevin Barry Memorial Committee. The Committee was formed to raise funds to create a memorial to Kevin Barry (20 January 1902–1 November 1920). Barry, a medical student at University College Dublin, was executed for his part in an ambush which resulted in the deaths of three British Army officers. The Committee commissioned Harry Clarke Stained Glass Limited to create a stained glass window dedicated to Kevin Barry and the other students and graduates of University College Dublin who lost their lives in the struggle for Irish Independence. The window, designed by Richard King, was erected in Earlsfort Terrace and unveiled on 1 November 1934. In 2010, the window was conserved, restored and relocated in the Charles Institute at Belfield, the current campus of University College Dublin.
