Anyone can post anything on the free Web, and anyone frequently does. A student who typed "Thomas Jefferson" into the Google search engine would get 1.29 million hits; rap star Eminem would bring up 1.37 million. Narrowing one's search to certain words may not help. The gamelike quality of screen and mouse encourages students to sample these sources rather than select an appropriate text and read deeply into it or follow an argument to its conclusion. The result is what Cooperman, who teaches both Davis and Flynn at Maryland, calls "cocktail-party knowledge."
