1. A system for providing an interactive electronic map, comprising: at least one computer programmed to cause a display device to simultaneously present thereon: a first portion of the map centered at a first x coordinate and at a first y coordinate; information on the first map portion related to one or more items associated with a geographic area represented by the first map portion; information outside of the first map portion responsive to a query relating to the map including user-selectable information; wherein the at least one computer is programmed to cause, in response to selection of user-selectable information from the user-selectable information outside of the first map portion and responsive to the query, the display device to simultaneously present thereon: instead of the first map portion a second map portion, in relation to the information selected, the second map portion being at least partially different from the first map portion and being centered at an x coordinate different from the first x coordinate, or at a y coordinate different from the first y coordinate, or at x and y coordinates different from the first x and y coordinates; information on the second map portion related to one or more items associated with a geographic area represented by the second map portion; information outside of the second map portion responsive to the query including user-selectable information; and additional information about the user-selectable information that was selected from outside of the first map portion; wherein the at least one computer is programmed to cause, in response to selection of user-selectable information from the user-selectable information outside of the second map portion which is different from the user-selectable information selected outside of the first map portion and responsive to the query, the display device to simultaneously present thereon: instead of the second map portion another map portion, in relation to the information selected, the another map portion being at least partially different from the second map portion and being centered at an x coordinate different from the x coordinate at which the second map portion was centered, or at a y coordinate different from the y coordinate at which the second map portion was centered, or at x and y coordinates different from the x and y coordinates at which the second map portion was centered; information on the another map portion related to one or more items associated with a geographic area represented by the another map portion; information outside of the another map portion responsive to the query including user-selectable information; and additional information about the user-selectable information that was selected from outside of the second map portion.
