Horace Worblehat, and that his fears of turning back into human are baseless at most - although with such a name, one could only surmise that he has a past to which he doesn't want to go back. The Art of Discworld confirms that the Librarian was indeed Dr. Horace Worblehat, which goes a long way to explaining why he's happier as an orang-utan than as a human. The Discworld Companion hints that he may once have been Dr. If the Librarian's true name were known, he could be changed back into a human, and he has therefore carefully excised his name from the records of the University (since he has special access). The Librarian's actual name has never been given in any of the books he is always simply "the Librarian". Both his language and his reaction were used separately and together as jokes in the first Discworld game. Nonetheless, most people seem to be able to understand him. He speaks an elaborate language whose vocabulary consists of the single word Ook (and its antonym "eek" - where "ook" means yes, "eek" tends to mean no). The Librarian is known for his violent reaction whenever he hears anyone refer to him as a "monkey" (orang-utans are apes).

The other wizards have gradually become used to the situation, to the extent that "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." ( Night Watch). He retained his position as librarian despite his condition because "he's the only one who knows where all the books are" and the fact that he could screw a man's head off with his feet. Most of the grimoires are highly dangerous to people, sometimes consuming them, but the Librarian is no person, and no longer requires a ladder to reach those tricky high-up shelves. Discovering that being an orang-utan has certain advantages for a librarian (climbing the book shelves and using his hands and feet for sorting books being one such advantage), he refused to be transformed back into a human, and has remained an orang-utan ever since. The Librarian first appeared in the first novel of the series, The Colour of Magic, and was transformed into an orang-utan in " The Light Fantastic" as the Octavo fired a beam of magic upwards (a sort of systemwide, in this case universe-wide, update intended to save the Eighth Creation Spell (and thus Rincewind) from falling off the disc). The Librarian of Unseen University is a character in Terry Pratchett's Discworld series of fantasy novels.
