A lumbrarian is a cross between a librarian and a lumberjack. It is a girl who wears their hair in a bun with glasses and looks put together from the neck up, but from the neck down wears a flannel and general manly lumberjack attire.
Wow, take a look at that lumbrarian chopping up books over there.
Is that a lumbrarian? Is she using the dewey decimal system to organize that lumber?
