The Orbis Cascade Alliance is a nonprofit consortium of 39 universities throughout the Pacific Northwest. They advance learning and research by combining the physical and digital library resources of their member universities to serve over 275,000 students. For my capstone, I constructed and conducted a series of tests designed to evaluate the Alliance’s catalog user interface and the information architecture through which they organize digital and physical materials. The results of these usability tests, card sorting activities, and interviews will help the Alliance to continue to promote academic success and better research.
