Lucas University Library was revered as the Interstellar Encyclopedia.
It housed a vast array of documents, recording the history of the Silver Star Empire and the chronicles of major planets.
Beyond this, there were materials on various academic subjects, everything you could think of.
It also included records on the differences among the races of various planets, which could be found here.
Xu Mo had chosen to be a librarian partly for this reason, as the Lucas University Library allowed the fastest understanding of interstellar matters.
Coming from Byron Star, he knew next to nothing about interstellar matters. Byron Star, having been rebuilt, had too few resources and was considered interstellarly ignorant.
