The Libraries' collections reflect the strengths of the university across disciplines. We provide demand-driven, network-based collections to the campus community in support of research and teaching. We are recognized as a national leader in building extensive research holdings in the areas of engineering, science, technology, and agriculture. Contact a subject specialist to discuss your collections needs.
