A computer instructor for an adult-education program at a community college became keenly aware of the gap in computer knowledge between his younger and older students. His observations were confirmed the day a new student walked into their library area and glanced at the encyclopaedia volumes stacked on a bookshelf. "What are all these books?" he asked. Somewhat surprised, the instructor replied that they were encyclopaedias. "Really?" he said. Someone printed out the whole thing?"
