Library & Research Service

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.

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.

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 application.


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.
