“Queer Ducks flock together.”
“Birds of a feather flock together?”
“Second hand books are wild books, homeless books; they have come together in vast flocks of variegated feather, and have a charm which the domesticated volumes of the library lack.”
“If it looks like a duck, quacks like a duck, it's a duck!”
“Without this flock, I would be worthless. Without the people in this flock, I'd be empty. Without the people who started this flock, I'd be dead.”
“If it looks like a duck and quacks likes a duck, it's a duck, right?”
