Expeditionary Library
this immense, underground library was maintained by the Chiss Epxansionary Defense Force, and contained written information on virtually every planet, moon, and star system ever encountered by the Chiss. It was unusual, not because it was underneath the ice, but because every volume contained in the Library was hand-written. This ensured that all the information was safe from computer glitches or power failures, reducing the overall power demands of the Chiss people. Without computers, unique search processed were developed to efficiently locate data in these books. When Luke Skwyalker arrived on Csilla to ask permission to traverse the Unknown Regions in search of Zonama Sekot, the leaders of the Chiss society would not allow him free access. However, they offered him two full days of research in the Library.
