The Irish Statute Book website, produced by the Attorney General's Office provides access to the full text (unofficial version) of all Acts of the Oireachtas. The print version is the official version and you will find it in the Government Publications section on the first floor of the O'Reilly Library on the Glasnevin campus.
The eIrish Statute Book "contains electronic versions of Acts and Statutory Instruments in the official language or languages in which they were enacted or made. Where an Act was enacted in both official languages (for example an Act to amend the Constitution) both official language versions are available on the eISB" (Irish Statute Book, 2016)
Full text versions of Acts of the Oireachtas are also available on the website of the Houses of the Oireachtas. Go to Bills and acts > Acts. This site is particularly useful because a link is provided alongside the Act to the Bill it initiated from, showing the stages the Bill came through before enactment.
