Nancy Pearl, the model for the action figure, looks a bit like that, but she doesn't dress like that. It's an deliberate stereotype, done as a joke. She's on the radio (local NPR affiliate) once a week, talking with the host about her latest reading recommendations. She's married (unlike the stereotypical old-maid librarian). I don't know if she has any kids. She's a bookaholic, reads very fast, and absorbs several books a week: all kindsa stuff, including mysteries, science fiction, general fiction, non-fiction. Good recommendations. I've read a lot of the stuff she's recommended, and she's never steered my to a book that I didn't agree was well worth reading.
She's also one helluva funny lady.
Libraries are a mark of a civilized society. In fact, I'm not sure civilization would be possible without them.
