Google Books Ngram is a Google Labs service that allows a person to scan Google's book database under several categories or "corpus"es (an example of a corpus being "American English", "British English", "French", et cetera) for specific words or phrases, and displays the percentage amount of said phrases' appearance in a line graph.
Stable. The Internet Archive keeps a public archive of the datasets (note, this is currently access restricted)
