This study focuses on a quantitative assessment of undergraduate student use of SFX citation linking software. The study seeks to reveal whether or not students are using SFX, and, if so, how they are using it. Study participants were Penn State Altoona students, all of whom had received basic library instruction. Their research sessions were captured with screen capture software and then coded with Studiocode video coding technology. While not the prime focus of the study, the investigators also considered the effect of factors such as database Web design, images, and terminology on student usage of SFX.
