- Eric, stylized as Faust Eric, is the ninth Discworld novel by Terry Pratchett. It was originally published in 1990 as a “Discworld story”, in a larger format than the other novels and illustrated by Josh Kirby. It was later reissued as a normal paperback without any illustrations, and in some cases, with the title given on the cover and title pages simply as Eric. (The page headers, however, continued to alternate between Faust and Eric.)
- The Librarian (Discworld) (Wikipedia)
The Librarian appeared in the second novel of the series, The Light Fantastic, where he was transformed into an orang-utan. This had certain advantages for a librarian, such as being able to use his hands and feet for re-shelving books. The other wizards have gradually become used to the situation, to the extent that, from Night Watch: “if someone ever reported that there was an orang-utan in the Library, the wizards would probably go and ask the Librarian if he’d seen it.”
