The focus of learning in any university is its library. At Carleton University, the MacOdrum Library houses more than a million volumes and almost a million other items that includes an increasing collection of microfilms, archival material, maps, slides, and other items. The library also subscribes to a large number of national and international journals and periodicals.

At the University of Ottawa, several specialized libraries exist, with a total collection of 1.4 million volumes and 3.4 million of other documents and material.
