I'm interested in four kinds of books: Graphic novels, books about video games, art references, and science books. These are the three kinds of books that are often shrinkwrapped in Barnes & Nobel and Border's Books. Why? You rarely see Jane Austin or self-help books shrinkwrapped. Why can't I crack open a graphic novel to see if I like the art or not?
EDIT: Glendon has an interesting idea, but I have to knock it down. Two books (which I own) that were NOT shrinkwrapped: Playboy: The Complete Centerfolds and The Big Book of Breasts. I flipped through those suckers in the store. But Batman: Mad Love and Evolution are taboo?
