Librarians appeared in other literature as well. For instance, Neal Stephenson's novel "Snow Crash" features a commercialized melding of the Central Intelligence Agency and the Library of Congress, along with a virtual librarian who assists the main character, and raises questions of the role of the librarian in an increasingly information-rich world. Also, the eponymous character in Garth Nix's "Lirael" (2001) is an assistant librarian whose curiosity about the library she works in leads her into trouble and whose research skills save her. The head librarian is intimidating and the library itself is a dangerous place. At the same time, in the Sune series, Sune's mother Karin is a librarian who does not like comic books, a reference to the comic book debates of earlier decades.
