The Library & Research Service (L&RS) provides information and research services to Members of the Oireachtas. Our mission is to contribute to a well-informed parliament.

The parliamentary library delivers information services and manages a collection of contemporary and historical material to meet the needs of our users. The parliamentary research service delivers impartial research briefings to support the work of the Houses, committees and individual Members.

Documents Laid

We manage the collection of documents formally laid before the Houses of the Oireachtas. Government Departments and agencies can lay documents before the Houses of the Oireachtas via our online Documents Laid form.


Our collections range from the 16th century right up to the present day. Search our online catalogue to access our Documents Laid collection and our historical collection.

Research and analysis

We produce a series of research publications for Members on key issues. These include monthly Economic Indicators, Spotlights, Bill Digests and L&RS Notes.

Bibliography of Parliament

Our new Bibliography of Parliament in Ireland lists works relevant to parliament in Ireland since the foundation of Dáil Éireann in 1919. You can use the bibliography to generate references to sources such as books, journal articles, web pages and conference papers.

Constituency dashboards

Constituency dashboards provide an interactive online visualisation of Census 2016 data for each Dáil constituency. They are a great way to get the information you need about your constituency.

Historical documents

We hold a collection of historical documents dating from the 16th century. You can explore this important collection by browsing our digital exhibitions or searching our online catalogue.
