The Library of Trinity College Dublin (Irish: Leabharlann Choláiste na Tríonóide) serves Trinity College and the University of Dublin. It is a legal deposit or "copyright library", which means that publishers in Ireland must deposit a copy of all their publications there, free of charge. It is also the only Irish library to hold such rights for the United Kingdom. The Library is the permanent home to the Brian Boru harp which is a national symbol of Ireland, a copy of 1916 Proclamation of the Irish Republic, and the Book of Kells. Two of the four volumes of the Book of Kells are on public display, one opened to a major decorated page and the other to a typical page of text. The volumes and pages shown are regularly changed. Members of the University of Dublin also have access to the libraries of Tallaght University Hospital and the Irish School of Ecumenics, Milltown.
The Library proper occupies several buildings, six of which are at the Trinity College campus itself, with another part of the Trinity Centre at St James's Hospital, Dublin:
