American English Corpus

A new 100+ million word corpus of American English (1920s-2000s) is now
freely available at:
http://corpus.byu.edu/time/
The corpus is based on more than 275,000 articles in TIME magazine from
1923 to 2006, and it contains articles on a wide range of topics –
domestic and international, sports, financial, cultural, entertainment,
personal interest, etc.
The architecture and interface is similar to the one used at the British National Corpus (see http://corpus.byu.edu/bnc)
