Increasing numbers of U.S. public libraries are eliminating overdue fines. While some public libraries have reported preliminary results of removing fines in their institution, there is a dearth of empirical studies on the potential effects of fine-free policies across public libraries. Using data retrieved from the Urban Libraries Council and End Library Fines, we identified 103 fine-free libraries from which we requested circulation, collections, and budget data. With this data we will test six hypotheses in an attempt to fill the gap in empirical evidence. The results will inform public policy on equitable access to public library services.
