A disproportionate number of the librarians represented in novels are in the detective fiction genre, frequently as an amateur detective and protagonist. Although the stereotype of the librarian as a "passive bore" does not seem reconcilable with the intensity of a mystery, the stereotypical librarian does share many traits with the successful detective. Their mindset is focused, calm, unbiased in considering viewpoints, and focused on the world around them. By personality they are industrious perfectionists—and eccentric. The drab and innocuous look of the stereotypical librarian is perfect for avoiding suspicion, while their research skills and ability to ask the right questions allow them to procure and evaluate the information necessary to solve the case. The knowledge they have gained from wide reading successfully competes with a private investigator's personal experience. For example, Jacqueline Kirby is drawn into the mystery in Elizabeth Peters' novel "The Seventh Sinner" (1972) due to her awareness of her surroundings. Wearing the stereotypical bun, glasses, and practical clothes, together with an eccentrically large purse, she is self-possessed and resourceful, knowledgeable in a variety of fields and skilled at research. Batgirl as Dr. Barbara Gorden in DC comics is depicted as working as librarian in Gotham City's Public Library.
