Abstract: When the COVID-19 pandemic hit the United States in March 2020, the University of North Texas (UNT) Libraries reacted quickly to increase online access and ensure that patrons had access to computers and internet by checking out laptops and mobile hotspots. Through all of this, the main location of UNT Libraries remained open, albeit with a mask requirement, safety equipment, and social distancing. With other library locations being closed to patrons, limited hours at the main location, and the risk of exposure to COVID-19, circulation of materials plummeted. However, despite these barriers to entry, certain patron groups continued to check out physical materials covering a wide variety of subjects from the library. However, there were changes to the distributions of checkouts by patron groups and item classifications. While some of these effects were short-term, others have persisted and potentially represent permanent changes to patterns of library usage. This paper examines the changes to physical circulation by item type, patron classification, patron major, and item subject for physical circulation, and it investigates changes to eBook usage during the same period.
