This study connects library user surveys, a common library assessment technique, to institutional data to demonstrate the value an academic library brings to student learning and student outcomes. Using regression techniques, the study identifies multiple significant correlations, both positive and negative, between student use of the library and student learning and outcomes as measured by retention, graduation, and grade point average (GPA). The library factors associated with student outcomes change over the course of the four-year undergraduate experience. Methods used in this study could be a model for other institutions seeking a means for assessing the library's relationship to student learning and outcomes. Contains notes.
