The rulebook for the first edition of Star Wars: The Roleplaying Game stressed that "there is no paper in the Star Wars universe" and that the inhabitants of the galaxy exclusively used electronic means of data storage. In addition to the use of paper in publications, such as Assault at Selonia, this attitude towards the use of paper in the Star Wars universe seemed to relax by the time that the rulebook for the game's second edition was published. It stated that paper was "rarely, if ever used" by the galaxy's inhabitants.
