The centre houses the Newman College Irish collection (O'Donnell Collection), which was formed in 1924 with a bequest to the college. It originally consisted of around 700 books and 300 pamphlets, many in the Irish language, which were the personal library of Nicholas O’Donnell, a Melbourne Irish language scholar of the early 20th century. Around half the collection consists of historical works. The rest deals with language, literature, biography, religion, politics, description and travel, with some works on music and a few on education.
