Ann L Holstein has published "Geographic Information and Technologies in Academic Research Libraries: An ARL Survey of Services and Support" in Information Technology and Libraries.
Here's an excerpt:
One hundred fifteen academic libraries, all current members of the Association of Research Libraries (ARL), were selected to participate in an online survey in an effort to better understand campus use of geographic data and geospatial technologies, and how libraries support these uses. The survey was used to capture information regarding geographic needs of their respective campuses, the array of services they offer, and the education and training of geographic information services department staff members. The survey results, along with review of recent literature, were used to identify changes in geographic information services and support since 1997, when a similar survey was conducted by ARL. This new study has enabled recommendations to be made for building a successful geographic information service center within the campus library that offers a robust and comprehensive service and support model for all geographic information usage on campus.
