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.

Pat was an Irish three-penny weekly satirical periodical, published and printed in Dublin by W. P. Swan. It was founded in 1879 by political cartoonist and illustrator John Fergus O'Hea, and writer and editor Edwin Hamilton. Hamilton and O'Hea had previously worked on the comic magazine Zozimus, the magazine Ireland's Eye, and the weekly newspaper Zoz. Pat was edited by Hamilton, with illustrations provided by O'Hea and other artists. Publishing ceased temporarily from September 1880 until January 1881, when O'Hea was joined by cartoonist Thomas Fitzpatrick. A summary printed in a number of issues describes the content as "artistic, literary, humorous, satirical… Each number contains, printed in several colours, one double page cartoon and one or more full page cartoons, besides numerous uncoloured sketches and minor illustrations. The literary matter, supplied by Irish writers of recognised ability, will treat of current events, not only in Dublin, but in all parts of Ireland". Regular features included a diary of the character Pat, reports on theatre productions in Dublin, descriptions of Dublin streets and areas, and travel notes from around Ireland and London. The illustrations cover many of the major political, social, and cultural issues of the period. Pat ceased publication in March 1883 and was followed by the short-lived magazine The Irish Diamond.

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.

The Dublin Town Planning Competition was held in 1914, with the aim to "elicit Plans and Reports of a preliminary and suggestive character, and thus obtain contributions and alternatives which may be of value towards the guidance of the future development of the City in its various directions". The Dublin civic survey report refers to the competition as the Aberdeen Competition, probably due to the prize for the best design which was presented by the Marquis of Aberdeen and Temair. Eight entries were submitted in total, each relating to the Greater Dublin area, taking in Howth, Glasnevin, Ashtown, Dundrum and Dalkey. The main headings for the proposals included: 1. Communications; 2. Housing; and 3. Metropolitan improvements. The submission by Patrick Abercrombie, Sydney Kelly and Arthur Kelly was awarded the prize in 1916. Due to major political and historical events, the winning entry was not officially published until 1922, with the final Civic Report not published until 1925. Out of the eight entries, only three are known to have survived.

The M. Michael Corcoran’s Photograph Albums contain photographs taken by Mother Michael Corcoran IBVM (1846-1927), Superior General of the Loreto Sisters. M. Michael was a self-taught photographer who used her camera to capture religious sisters, ministries, pupils, employees and friends of Loreto communities in Ireland and across the world. In 1902, M. Michael became the first Superior General to undertake a visitation of the IBVM communities in India and Australia and her photographic collection consists mainly of images captured during this international visitation. The albums also include images of Loreto Abbey, Rathfarnham taken in 1905 and images of Loreto Convent, Balbriggan taken between 1906 and 1907. Her albums should be of interest to anyone interested in M. Michael Corcoran IBVM as an educator or as IBVM Superior General, researchers interested in early 20th century photography, local history, early 20th century convent or school life in Ireland, and in foreign provinces.
