Abstract
An information presentation system that simplifies entry of information relating to a package media of a user. The information presentation system includes a playback apparatus, a library information management apparatus, and a terminal apparatus. The playback apparatus reads an identifier identifying a content from a portable recording medium in which the content is recorded, and transmits the read identifier to the library information management apparatus via a network. The library information management apparatus receives the identifier, acquires attribute information, generates library information including the attribute information and the identifier, and stores the library information. Upon request by the terminal apparatus, the library information management apparatus generates presentation information based on the library information, and transmits the presentation information.
