Description	The Corpus of Contemporary American English (COCA) contains about 1 billion words in nearly 500,000 texts from 1990 to 2019 -- which are nearly evenly divided between spoken, fiction, magazines, newspapers, academic journals, blogs, other web pages, and TV/Movie subtitles (120-130 million words in each genre). In addition, there are 20 million words each year from 1990-2019 (with the same genre balance each year). From the COCA website:"The Corpus of Contemporary American English (COCA) is the only large and 'representative' corpus of American English. COCA is probably the most widely-used corpus of English, and it is related to many other corpora of English that we have created. These corpora were formerly known as the 'BYU Corpora', and they offer unparalleled insight into variation in English. (https://www.english-corpora.org/coca/) (2022-09-02)

Restrictions on use of the English Corpora materials

You must agree to these restrictions in order to obtain the data

In no case can substantial amounts of the full-text data (typically, a total of 50,000 words or more) be distributed outside the organization. For example, you cannot create a large word list or set of n-grams, and then distribute this to others, and you could not copy 70,000 words from different texts and then place this on a website where users from outside your organization would have access to the data.
If portions of the derived data is made available to others, it cannot include substantial portions of the the raw frequency of words (e.g. the word occurs 3,403 times in the corpus) or the rank order (e.g. it is the 304th most common words). (Note: it is acceptable to use the frequency data to place words and phrases in “frequency bands”, e.g. words 1-1000, 1001-3000, 3001-10,000, etc. However, there should not be more than about 20 frequency bands in your application.)
You can not use the data to create software or products that will be sold to others.
Students in undergraduate classes cannot have access to substantial portions of the data (e.g. 50,000 words or more). Graduate students can have access to the data for work on theses and dissertations. The data is primarily intended for use in research, not teaching. If you need corpus data for undergraduate classes, please use the standard web interface for the corpora at https://www.english-corpora.org/
Any publications or products that are based on the data should contain a reference to the source of the data: https://www.corpusdata.org.
