Abstract: An information management system in which information related to a spatial location is registered and at least a part of the information is outputted by using a spatial condition as a clue. A space is pre-divided in a plurality of unit zones and the space is again re-divided in another plurality of unit zones (102, 103). The system has Information input means 12 enabling an information provider 11 to input information including a desired spatial location and DB registration means 134 enabling inputted information to be registered in a database (DB) 105. The system also has request input means 142 enabling an information recipient 12 to input a request including a desired spatial condition, DB retrieving means 144 enabling information to be selected in an information DB 105 in response to an inputted request, and information output means 145 enabling selected information to be outputted.
