All 680 pages of the Book of Kells can be explored on a new app for the iPad.
The Book of Kells for iPad was designed and developed by X Communications, a campus company, in collaboration with Trinity College Library.
It allows users to scroll through the 1,200-year-old manuscript page by page.
High resolution images of the most highly decorated pages are included at up to six times their original size.
The developers describe the biggest challenge in building the app as "handling the huge amount of content both from an organisational perspective and a program efficiency point of view".
