The Oxford English DictionaryCall Number: ONLINE
Guide to the meaning, history, and pronunciation of 600,000 words— past and present—from across the English-speaking world.
As a historical dictionary, the OED is very different from dictionaries of current English, in which the focus is on present-day meanings. You’ll still find present-day meanings in the OED, but you’ll also find the history of individual words, and of the language—traced through 3 million quotations, from classic literature and specialist periodicals to film scripts and cookery books.
