Librarium Terra
From Warhammer 40k - Lexicanum
The Librarium Terra is a structure on Terra itself that serves as a repository of knowledge for the collected information of the Imperium of Man, situated deep within the crust of the planet itself and contained in a labyrinth of corridors where towering rows of bookcases and datastacks are located. Within the Librarium, billions of souls work through the bureaucracy that keeps the Imperium together. Amongst its contents are included particularly pure as well as dangerous history[1a], along with details of the Imperium's armed forces, Imperial Guard regiments, and various military campaigns.[1b]
