Trinity College Library

The Library of Trinity College Dublin serves Trinity College and the University of Dublin. It is the largest library in Ireland and, as a legal deposit or "copyright library", it has rights to receive material published in the Republic of Ireland 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 famous Book of Kells. Two of the four volumes 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 Hospital and the Irish School of Ecumenics, Milltown.

The Library proper occupies several buildings, four of which are at the Trinity College campus itself, with another part of the Trinity Centre at St. James's Hospital, Dublin:

• The original (Old) Library is Thomas Burgh’s masterpiece. A huge building, it originally towered over the university and city after its completion. Even today, surrounded by similarly scaled buildings, it is imposing and dominates the view of the university from Nassau Street. The Book of Kells is located in the Old Library, along with the Book of Durrow, the Book of Howth and other ancient texts. Also incorporating the Long Room, the Old Library is one of Ireland's biggest tourist attractions, and holds thousands of rare, and in many cases very early, volumes. In the 18th century, the college received the Brian Boru harp, one of the three surviving medieval Gaelic harps, and a national symbol of Ireland, which is now housed in the Library. Housed within the Old Library are:

• Early Printed Books & Special Collections

• Manuscripts & Archives Research Library (M&ARL)

• The Berkeley/Lecky/Ussher (BLU) Arts Libraries complex, incorporating:

• The Berkeley Library, in Fellows Square

• The Lecky Library, attached to the Arts Building

• The Ussher Library, overlooking College Park

• The Glucksman Map Library

• The Preservation and Conservation Department

• The Hamilton Science and Engineering Library

• The 1937 Reading Room (for graduate use)

• The John Stearne Medical Library (JSML), housed at St James's Hospital

The Library began with the founding of Trinity College in 1592. In 1661, Henry Jones presented it with the Book of Kells, its most famous manuscript. James Ussher (1625–56), Archbishop of Armagh, whose most important works were "Veterum Epistolarum Hibernicarum Sylloge" (1632) and "Brittanicarum Ecclesiarum Antiquitates" (1639), left his valuable library, comprising several thousand printed books and manuscripts, to the Library. His complete works were published by the Library in twenty-four volumes.

According to the Republic of Ireland's Copyright and Related Rights Act, 2000, the Library is entitled, along with the National Library of Ireland and the libraries of the National University of Ireland, the University of Limerick, and Dublin City University, to receive a copy of all works published in the Republic of Ireland. Also, as a result of the British Legal Deposit Libraries Act 2003, which continues a more ancient right dating from 1801, the Library is entitled, along with the British Library, the Bodleian Library at Oxford, Cambridge University Library, the National Library of Wales and the National Library of Scotland, to receive a copy on request of all works published in the United Kingdom.

The 65-metre-long (213 ft) main chamber of the Old Library, the Long Room, was built between 1712 and 1732 and houses 200,000 of the Library's oldest books. Initially The Long Room had a flat ceiling, shelving for books only on the lower level, and an open gallery. By the 1850s the room had to be expanded as the shelves were filled due to the fact that the Library had been given permission to obtain a free copy of every book that had been published in Ireland and Britain. In 1860, The Long Room's roof was raised to accommodate an upper gallery.

The Long Room is lined with marble busts. The marble bust collection was formed when 14 busts from the famous sculptor Pieter Scheemakers were acquired by the college. Many of the busts are of great philosophers, writers, and men who supported the college. The most outstanding bust in the collection is of the writer Jonathan Swift, created by Louis François Roubiliac.
