To deal with self-selection bias and estimate this impact more accurately, we used propensity score matching. Using this unique approach allowed us to construct treatment and control groups with similar background characteristics. We found that using a given library resource was associated with a small, but also meaningful, gain in first-term grade point average, net of other factors.mid budget cuts and legislative pressure, academic institutions are increasingly seeking ways to foster student success. Colleges and universities often create and/or expand support services and programmatic interventions, with the hope that these services will yield positive returns, such as higher student persistence rates and better grades. Student support services, in turn, are increasingly asked to demonstrate their worth in terms of contributing to the achievement of institutional outcomes. Academic libraries are not an exception.
