A method of providing information to a user via a printed substrate, said substrate comprising a graphic image and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said method comprising the steps of: receiving, in a computer system, interaction data indicative of the region identity and at least one position of a sensing device relative to the image, the sensing device generating the interaction data when operatively positioned or moved relative to the image by reading at least some of the coded data; identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity, generating a query expression comprising one or more search terms, at least one of said search terms being associated, in the page description, with a zone of the graphic image containing the position of the sensing device; forming a request using the query expression; and sending the request, or a results resource including search results obtained using the request, to the user.
