ABSTRACT
The mobile revolution, the fastest diffusion of technology in human history, is rapidly changing the future of reference services. Using personal, portable information, communication, and entertainment (PP ICE) devices to ask and receive reference information is not just another in the growing list of reference communication channels. PP ICE reference fuels mobile information experiences, which are integrated more closely with what one is doing and thinking at the moment. To be useful in the mobile era, library reference services need to overcome the reference desk mentality and the schedule fetish. Because of the mobile revolution, social search will rise again.
