The Library Data database is assembled by the servants of the Emperor with the aim of providing the interstellar traveller with an accurate, up to date source of information about the Imperium, its worlds, and its surroundings. Included are entries on the major subjects most commonly requested by interstellar travelers. The system allows for continual updating and expansion by connecting your portable database to a local Imperial computer system. To avoid filling too much memory space (always precious on a starship’s computers), a large portion of the data is stored off-line, requiring specific action on the part of the operator. However, the most important core information may be immediately accessed by anyone with a minimum of computer literacy. It should be noted that the updating of the data tends to result in the content of a particular library being biassed towards the area in which the updating occurs. The core information is prefaced by the Emperor’s List, a useful aid to viewing Imperial history. Following this is an alphabetical listing of the greater portion of the library’s core data. Finally, there are essays on major aspects of Imperial society, etc. Travelers are encouraged to update and add entries based on their own experiences, which in turn adds to the great knowledge of the Imperium.
