Answering questions about library impact on student learning

“This essay reports on a project which evaluated the Understanding Library Impacts (ULI) protocol, a suite of instruments for detecting and communicating library impact on student learning. The project was a dissertation study conducted with undergraduates enrolled in upper-level and capstone history classes at six U.S. colleges and universities in 2011.
