The Corpus of Contemporary American English is the first large, balanced corpus of contemporary American English. It is freely available online…The corpus contains more than 385 million words of text, including 20 million words each year from 1990-2008, and it is equally divided among spoken, fiction, popular magazines, newspapers, and academic texts. (The most recent texts are from late 2008). The corpus will also be updated every six to nine months from this point on, and will therefore serve as a unique record of linguistic changes in American English.
