A chronology of events relevant to the history of the OED
1857 At the suggestion of Frederick J. Furnivall, the Philological Society of London establishes ‘a Committee to collect unregistered words in English’. Richard Chenevix Trench delivers a paper On some Deﬁciencies in our English Dictionaries to the Society.
1858 The Society resolves to begin preparing a new dictionary of English.
1859 The Society produces its Proposal for the Publication of a New English Dictionary (usually abbreviated as NED). Herbert Coleridge is appointed as its ﬁrst editor. An appeal is made for American scholars to help the project by ‘reading books and noting words’ for inclusion.
1861 Coleridge dies, and Furnivall is appointed as editor in his place.
1879 Oxford University Press agrees to publish and ﬁnance the project, and James Murray, president of the Philological Society, is appointed editor. Murray issues An Appeal to the…English-Reading Public to read Books and make Extracts for the…New English Dictionary.
1884 The ﬁrst part or fascicle of the NED, covering A–Ant, is published on 29 January (1 February in the United States).

1915 James Murray dies, and Henry Bradley becomes the senior editor at work on the dictionary.
1919 J. R. R. Tolkien joins the NED for a little over a year, working on words beginning with W.
1923 Henry Bradley dies, leaving Craigie and Onions to complete the project.

1986 The fourth and ﬁnal volume of the Supplement appears. John Simpson, who has been working on the Supplement, joins Weiner as co-editor of the New OED.

1989 The second edition of the Oxford English Dictionary (OED2) appears in print as 20 volumes containing 21,728 pages and costing £1,500. It deﬁnes over half a million words (including 5,000 added since the Supplement), and is illustrated by more than 2.4 million quotations.
1992 OED2 becomes available on CD-ROM.
1993 John Simpson is appointed Chief Editor, and work begins on the ﬁrst wholesale revision of the Dictionary—the Third Edition, or OED3. The ﬁrst two volumes of Additions are published.

2009 A Historical Thesaurus of the OED appears, providing a systematic inventory of 800,000 senses from the OED and other sources.
2010 Alphabetical revision reaches the end of R, meaning that OED3 entries from M–Ryvita are now online.
2013 John Simpson retires, and Michael Proffitt is appointed Chief Editor.
2020 The OED currently defines more than 636,000 lexical items, with around 864,000 separate senses, illustrated by over 3.7 million quotations drawn from over 1,000 years of the written history of English. More than forty percent of the dictionary has been revised, with new and revised words from across the alphabet appearing each quarter.
