From our newspaper today:
"We had sat around and griped and griped and griped about how poorly Kentucky authors were treated, even in Kentucky," said KaBooM member Mary Alexander, 54, a fiber artist from Harrodsburg. "Bookstores didn't take us seriously, so we started going around and reorganizing their shelves."

With permission?

"Not necessarily," Alexander said. "That's why we called it the book mafia."
