The Oxford English Corpus (OEC) consisted mainly of websites chosen in the way of presenting all types of English, from literary novels to everyday newspapers and the language of blogs and even social media. Besides UK and US English there are Englishes from Ireland, Australia, New Zealand, the Caribbean, Canada, India, Singapore, and South Africa. The last version of this corpus contains nearly 2.1 billion words (almost 2.5 billion tokens).

The corpus is supplied by Oxford University Press.
