Infinidim Enterprises Infinidim Enterprises is the name of a publishing corporation in Douglas Adams ' book Mostly Harmless , fifth of the Hitchhiker 's Guide to the Galaxy trilogy . Infinidim buys out the original publisher of the Guide , Megadodo Publications , with plans to sell to affluent people , rather than poor hitchhikers . The company could possibly be a front organization for the Vogons , who are employed by it . Apart from its ownership of the guide , we also learn that its head editor is named Vann Harl ( though in the radio series it is in fact Zarniwoop ) . Ford Prefect tries to over-throw Infinidim by stealing the new guide and sending it to Arthur Dent for 'safety ' ( whether his or Arthur 's is anyone 's guess ) . The fate of Infinidim at the end of the series is unknown .
