About OED Online

The Oxford English Dictionary, the world's leading authority on the history and development of the English language since 1150, is now available online.

In addition to offering unparalleled access to the wealth of material contained in the 20-volume Oxford English Dictionary and 3-volume Additions Series, online publication enables the ‘treasure-house’ of the English language to move with the times as never before.

For the first time since it was completed in 1928, the Oxford English Dictionary is being completely revised; every word and every sense is being fully reviewed, and new words added, to take account of the latest changes in language and scholarship.

New material from the £34 million (US$55 million) revision programme, which began in 1993, is released quarterly, offering online subscribers a unique opportunity to follow the progress of the revision project.
