The Oxford English Dictionary (OED) is now available online to students and staff. The OED is widely regarded as the accepted authority on the English language. It is an unsurpassed guide to the meaning, history, and pronunciation of more than 600,000 words—past and present—from across the English-speaking world.
The OED can be found on the library’s webpage Encyclopedias & dictionaries, via the link Databases and in some of the subject guides.
