Historical Thesaurus of the Oxford English Dictionary

Today marks the official launch of the largest thesaurus resource in the world, covering more than 920,000 words and meanings, based on the Oxford English Dictionary. Editors Christian Kay, Jane Roberts, Michael Samuels and Irene Wotherspoon have compiled the first historical thesaurus for any of the world's languages. It lists synonyms with the dates of first recorded use in English, in chronological order, with earliest synonyms first.
