This document summarizes the findings and recommendations from a Library of Congress Teaching with Primary Sources grant program at the University of Arizona. Over two years, librarians partnered with faculty from various disciplines to develop primary source lessons and materials for undergraduate and graduate courses. They created a primary sources portal and engaged the campus community through workshops and a symposium. The partnerships helped increase faculty and student skills and confidence in searching, analyzing, and teaching with primary sources. Moving forward, the program aims to support additional collaborations, online resources, and workshops.
