The Librarian is a character from Glee first introduced in Bad Reputation, the seventeenth episode of Season One. She is seen as cranky and moody, a typical stereotype of librarians, yet she does soften up at times. In the credits, she is always listed as "Ancient Librarian." She has only had one speaking line, which was in Bad Reputation.
She was portrayed by the late actress Jean Sincere.
She is seen watching Artie, Tina, Mercedes, Kurt, and Brittany's performance of U Can't Touch This. She then asks if the kids would perform that for her Sunday Service and commented that it was 'very cute'.
She warns Tina and Mike to be quiet when they are fighting in the library.
She doesn't appear in this episode, but Rachel is seen instead of her during Artie's Dream. According with it, if New Directions hadn't existed, Rachel would have become the new librarian after graduating.
