Just as English is a very large and complex language, so the OED is a very large and complex book. It defines well over half a million words. It contains scores of millions of characters, and, at least in its early versions, many miles of hand-set type. Its enormous—and enormously heavy—volumes are bound in dark blue cloth: Printers and designers and bookbinders worldwide see it as an apotheosis of their art, a handsome and elegant creation that looks and feels more than amply suited to its lexical thoroughness and accuracy.
