This poster describes an innovation put in place at the University of Limerick’s Glucksman Library to counter the student practice of reserving library desks. This single site study used mixed methods to explore the phenomenon of students reserving library seats, and to measure the impact and effectiveness of an intervention put in place to alleviate the space constraints caused by the practice. The data from focus groups and surveys provides an understanding of the problem before and after the intervention. The desk clearing initiative described in this study was successful in reducing the practice of seat reserving and thus increasing the availability of seats for use. This research gives library managers practical advice about how to tackle the problem of seat reserving in libraries.
