As a student of DCU, the Library will play a key role in supporting your learning and study throughout your time at DCU. The Library spans the University’s three campuses: O’Reilly Library on the Glasnevin Campus, Cregan Library on the St. Patrick’s Campus, and the newly opened Woodlock Hall Library on the All Hallows Campus.

When you start in September be sure to participate in your local campus library Orientation programme, where you will become familiar with the library spaces and learn about the many services and supports we have to offer. 

Students have access to a number of services and facilities including individual study spaces, borrowing of print books, wifi, photocopying, scanning and printing, access to PCs and Laptops, Group Study Rooms, online library guides and classes and workshops. Library desk staff are on hand at all three sites to help you locate materials and make the most of your library experience.

Explore the wide array of library collections from our online discovery tool ‘Library Search’: print books, eBooks, online journals and databases, newspapers, theses & dissertations and so much more.  The online Library is accessible from the library website and is available 24/7 on campus or from home. Sign in with your DCU student network log in to get full access to all of the library's extensive range of academic content.

Chat with library staff live through our online chat service ‘Chat With Us’. Ask a question and you will receive an immediate answer.

Maths Learning Centre:

All kinds of courses in DCU have a mathematics module as part of their degree programme. Sometimes students need a little extra help with mathematics, and that is where the Maths Learning Centre comes in! Its role is to provide informal mathematical support in a welcoming environment. The Centre is located on the ground floor of the Glasnevin Campus Library. Here you can receive extra one-to-one maths tuition on a drop-in basis with experienced tutors. This service is free of charge and highly recommended by students. You can also use the Centre as a maths study space, where you can work at your own pace and a tutor will be on hand if you have any questions.
