Briefly, in order to use an external store of information, people must maintain a reduced internal representation along with a pointer to the external store. An external store will not be useful unless it significantly relieves the internal store from the burdens of quantity and persistence. I would be very interested in hearing criticisms of Schonpflug's work as well as more pointers to other research. Schonpflug, W. "External Information Storage: An Issue for the Psychology of Memory."
