Georgia State University (GSU) affiliates must swipe their campus ID cards at turnstiles in order to enter the University Library buildings. The swipe verifies the individual is a GSU affiliate and unlocks the turnstile for entry. With each swipe, data such as year in school, major, and GPA are sent to a database. The library partnered with Advanced Campus Services, (ACS), GSU‟s high-performance, research computing unit, to create a tool to access the data. The end product has been a valuable tool for the library, one that has been used to inform staffing and operating hours decisions, as well as produce reports for campus stakeholders.
