The online Oxford English Dictionary is a work in progress. Hundreds of new entries are added every year. The OED is currently being revised, with the aim of producing a completely updated third edition. Draft material from the revision programme is published online, alongside unrevised entries from the 20-volume Second Edition, first published in 1989, and its 3-volume Additions Series, published in 1993 (volumes 1 and 2) and 1997 (volume 3). Many of the entries in the Additions volumes consist of sections which are additions to an entry previously published in the Second Edition; such sections are appended to the end of the appropriate Second Edition entry. Complete entries published for the first time in the Additions volumes are presented as free-standing entries, along with entries from the Second Edition.
