Geographic Information System (GIS) technology can be employed by academic librarians to study interlibrary loan (ILL) lending patterns of circulating materials. The data collected and analyzed using GIS can apprise librarians about the efficacy of existing networks, assist them in making sound cost-saving choices, and inform collection development activities. In this article, the physical lending outputs at The University of Alabama are studied across five years to understand better and explore factors that impact lending activities within Alabama. The data retrieved elucidate stable patterns and highlight identifiable changes in usage that can inform subsequent lending network practices within the state. The totality of this data can aid toward the desired outcomes of enhanced resource sharing as it relates to ILL practices.
