::Yup, at least some stories, and the 1960s show, have Barbara Gordon employed as a librarian. But only that character, not the other 4 that branch off of this dab page. The cats for this article should be limited to those that apply to all 5 characters. That means that the following (based on current cats):
DC Comics superheroes
DC Comics titles
American comics characters
Fictional vigilantes
These should not be here since they are not shared across the board:
Comic book sidekicks (Misfit has not really been a sidekick)
DC Comics martial artists (Misfit, again)
Fictional detectives  (Only covers Barbara, may cover Helena and Cass)
