Abstract: The central apparatus accepts headline information, authorized user information, and storage location information and stores the accepted browsable information etc. in association with the storage location information. When a user has transmitted identification information for identifying the user from his terminal apparatus to the central apparatus, the central apparatus receives the identification information. The central apparatus extracts the headline information and the storage location information based on the received identification information and the registered authorized user information. Based on the extracted headline information and storage location information, the central apparatus generates a hyperlink and then generates an HTML document containing the generated hyperlink. The generated document is then transmitted to the terminal apparatus of the user.
