Although many libraries already offer some type of reference service geared toward people who use mobile devices, they generally focus on the reference transaction and not on some of the broader aspects of service, including availability of content for mobile devices and relationship of the library's services to mobile initiatives on campus. Asking the right questions during the planning process can assist librarians in clarifying their goals for the service, identifying units to work with on campus, and determining whether the service is successful. This is a rapidly developing area and flexibility is key.
