For a recent comparative literature class paper, Brendan Draper wanted to quote a phrase from a novel he’d read, but he couldn’t remember what page it was on. He typed ââ?¬Å?nervous conditionââ?¬Â into Internet search giant Google’s index of books. Within seconds, he found the phrase and page number of the book. ââ?¬Å?It was extremely helpful,ââ?¬Â says Draper, 20, a student at the West Chester University of Pennsylvania.
