St. Patrick's boasts an extensive library of books and digital resources where pupils can consult encyclopaedias, atlases and dictionaries, and borrow novels, storybooks, and magazines. Pupils can also use the library to study and do homework at lunchtime and after school (study hours: 12:30-14:30 and 15:00-18:00).

A librarian is on hand at all times to assist the pupils and supervise the library.
