Oxford English Dictionary editor at large describes decades-long process of revision
Since its first publication in 1928, the Oxford English Dictionary — at 20 volumes, the most comprehensive historical dictionary in the world — has only been revised once in 1933, and republished once with supplemental material in 1979. And though Jesse Sheidlower's job as the dictionary's editor at large for North America is to spend his days updating, revising and adding new entries, there's no guarantee that there will ever be an OED 3.
