“English-Corpora.org is the most widely used collection of corpora (highly searchable collections of texts) anywhere in the world. The corpora are used by more than 130,000 people each month, from more than 140 countries. In addition, hundreds of universities worldwide have academic licenses, which provide their users with expanded access to the corpora.
The corpora have been used as the basis of thousands of academic articles, theses, and dissertations, and they form the backbone of courses on language and linguistics throughout the world, at all levels of instruction. Virtually every book on “teaching English with corpora” in the last 5-10 years has focused primarily on these corpora (which are also sometimes called the “BYU Corpora”, for the university where they were created). Since the first corpora were released in 2005, a total of seventeen corpora have been created.”
