Things Found in Books

I've been reading Moby Dick, a copy that previously belonged to my grandparents, and in it I found an article from the Cleveland Plain Dealer from the early 1960s on polar bears, and why they are the "nastiest" creatures in the zoo. For the life of me, I can't imagine why anyone in my family would have cut it out (from two different pages), much less tucked it safely away in a book.
