This document summarizes three projects at North Carolina State University Libraries that utilize mobile technology to better integrate in-person and online library services. The projects discussed are WolfWalk, which provides a mobile tour of campus history; Suma, a system for collecting and analyzing data on physical space usage; and an iPad kiosk application to provide reference help. The presentation considers how mobility can be used to reach new users, extend in-person services, better understand space usage, and enhance staff performance.
