What percentage of research papers that you now grade have only Internet citations? Yes, I know, way too many. Brace yourself, because this trend is not going to change anytime soon. Google is now the search engine of choice for many students. Left to their own devices, students collect information indiscriminately on the free Web and hand in papers and projects with works-cited pages that look like the greatest hits of Google. However, the situation is not hopeless. Faculty can insist that students base their research on what I term the resource trifecta.
