In 1989, using the new abilities of the computer, Oxford University Press issued its fully integrated second edition, incorporating all the changes and additions of the supplements in twenty rather more slender volumes. To help boost sales in the late seventies a two-volume set in a much-reduced typeface was issued, a powerful magnifying glass included in every slipcase. Then came a CD-ROM, and not long afterward the great work was further adapted for use on-line.
