« The corpus contains more than 360 million words of text, including 20 million words each year from 1990-2007, and it is equally divided among spoken, fiction, popular magazines, newspapers, and academic texts. The corpus will also be updated at least twice each year from this point on, and will therefore serve as a unique record of linguistic changes in American English. The interface allows you to search for exact words or phrases, wildcards, lemmas, part of speech, or any combinations of these. You can search for surrounding words (collocates) within a ten-word window (e.g. all nouns somewhere near chain, all adjectives near woman, or all verbs near key). »
