The struggle over what history is and how it should be told affects even such a constant convention as the footnote. As Anthony Grafton tells us in his entertaining study
The Footnote, this tool of scholarship is just that: a tool that marks the professional from the amateur. "Like the high whine of the dentist's drill," he says, "the low rumble of the footnote on the historian's page reassures: the tedium it inflicts, like the pain inflicted by the drill, is not random but directed, part of the cost that the benefits of modern science and technology exact." There are some scholars, Grafton avers, who consider the footnote an anachronism meant to distance people from their pasts. Conversely, there are some who wage whole wars against other scholars through the medium of their notes. In any event, Grafton opines, the footnote will prevail, protecting works of scholarship from assault as surely as armor protects a tank.
