Oxford English Dictionary

What Oxford English Dictionary does

The Oxford English Dictionary (OED), published by Oxford University Press (a department of the University of Oxford), is the principal historical dictionary of the English language, documenting the meaning, history, etymology, pronunciation, and usage evidence of over 500,000 words and phrases. The OED began as the New English Dictionary in 1884, with the complete First Edition published in 1928, and the Second Edition in 1989; it is currently undergoing a complete revision for the Third Edition. The online platform at oed.com, launched in 1992, is updated quarterly and integrates the core dictionary, the Historical Thesaurus of the OED (a semantic-category mapping of word usage over time), an AI Search Assistant (capped at 10 queries per day, retrieval-only), live-voice pronunciation recordings across British, U.S., and World English varieties, and a modern frequency corpus of 20 billion words covering 2017 to present. The product suite also includes the World Englishes program (with regional consultants across Africa, Asia, and beyond), the Oxford Dictionary of African American English (ODAAE, developed with Harvard's Hutchins Center), Word Stories, Word Lists, and the Word of the Day email program.

The OED operates a subscription-based business model with two primary revenue streams: personal individual subscriptions (starting from £10/$10 annually) and institutional subscriptions for universities, schools, and libraries (with Shibboleth and library card authentication, pricing undisclosed and contract-based). One-time revenue comes from physical print editions sold via OED's own storefront. Distribution is direct through oed.com and through library and academic institutional channels globally, with a Low and Middle Income Countries Initiative supporting accessibility. Customers span academic researchers, educational institutions, language enthusiasts, and World Englishes scholars, with marketing conducted through content marketing, email newsletters, YouTube, webinars, and academic conferences such as the Oxford World English Symposium. The product is differentiated primarily by its 140+ year editorial history, the depth of its citation evidence base, and its unique coverage of global English varieties, with the parent organization's academic mission and brand providing a structural moat against commercial substitution.
