The Carleton University Library, or more specifically, the Maxwell MacOdrum Library, was, hands…read moredown, my most valuable resource when I was a student there.
There are five floors full of material. There are books, newspapers, magazines, journals, government documents, archives, manuscripts, data and research material, CDs, DVDs, and many other types of media, including digital files. There are floors and sections of literature with a very great selection, but, in my opinion, much of the material here is used for something course-related. By that I mean students will raid the library to find statistics, articles in peer-reviewed journals, class readings, theses, and anything else they need to complete assignments, take exams, or for more clarification on course content. I was all about their online journals - I took full advantage of this great resource! It's fast and easy to do searches for the articles and within the articles themselves, and even better when the weather is terrible out and you'd rather stay in and still do research.
If you still can't find what you're looking for here or through their website for files digital format, you can always take advantage of their inter-library services, which allow you to borrow material from other libraries, like Ottawa U, for instance.
The library also has study spaces and group study rooms, individual tables and chairs on each floor, photocopy machines, computer labs, and even a self-checkout machines. If you need to talk a little louder or want to have more casual discussions while studying, you can try to grab a table at tunnel level.
Because the library right in the heart of the Quad on campus, it's always rammed with students. There is a cafe that sells coffee, tea, sandwiches, and snacks. It also has tables and couches, generally with every seat already taken but another student cramming for something.
