There are 5 Libraries in UCD. The James Joyce Library at Belfield which is the administrative centre of the library system: it accommodates the central services and 85% of the stock; the Health Sciences Library (for medicine, nursing and physiotherapy) located in the UCD Health Sciences Centre at Belfield; The Richview Library (for architecture, landscape and planning) in the Richview/Newstead precinct at Belfield; The Veterinary Medicine, located in the Veterinary Sciences Centre at Belfield; and the Blackrock Library at the UCD Blackrock Campus.

The Library as a whole contains over 1,000,000 volumes, with substantial collections of microforms and smaller collections in other print and non-print formats, including e-books in numbers approaching that of the print collection. Around 80% of stock is on open access. Approx. 84,000 current journal titles and databases are available, the vast majority of which are e-journals. The Library is a European Documentation Centre, and a legal deposit library for Irish publications and United States Government publications.

A small but significant holding of some 30,000 early printed books and special collections is housed in a separate Special Collections Library and we also encompass UCD Archives and the National Folklore Collection UCD.
