Bibliothek der klassischen Bücher transforms the Nintendo DS family of products into a library of timeless German-speaking literature, highlighted by 100 works from authors such as Johann Wolfgang von Goethe, Friedrich Schiller, Franz Kafka, Heinrich von Kleist and more. Readers can adjust the size of text, place bookmarks and even download new content via the Nintendo Wi-Fi Connection service (broadband Internet connection required). As of May 20, 2014, the Nintendo Wi-Fi Connection service for Nintendo DSi and Wii systems has been retired. Online features of this game are no longer available after this date but this game still provides an entertaining experience in offline mode.
