"Shakespeare was not even able to perform a function that we consider today as perfectly normal and ordinary a function as reading itself. He could not, as the saying goes, "look something up." Indeed the very phrase--when it is used in the sense of "searching for something in a dictionary or encyclopedia or other book of reference"--simply did not exist. It does not appear in the English language, in fact, until as late as 1692, when an Oxford historian named Anthony Wood used it. Since there was no such phrase until the late seventeenth century, it follows that there was essentially no such concept either, certainly not at the time when Shakespeare was writing--a time when writers were writing furiously, and thinkers thinking as they rarely had before. Despite all the intellectual activity of the time there was in print no guide to the tongue, no linguistic vade mecum, no single book that Shakespeare or Martin Frobisher, Francis Drake, Walter Raleigh, Francis Bacon, Edmund Spenser, Christopher Marlowe, Thomas Nash, John Donne, Ben Jonson, Izaak Walton, or any of their other learned contemporaries could consult."
