Campion just described his visit to this solar system sized library where the librarians' approach to immortality is to just continual grow throughout their lifetimes and where he was literally swallowed and then excreted so that he could upload his "trove" into a librarian. Oh, and a "short-term" access period to the library is 200 years. Of course, he used up at least a couple decades just trying to get them to talk to him.
