It looks as if Google assembled the largest collection of words
ever gathered online !
These words have been taken "from 5 million books published over the past four centuries."
All of these words have become part of a database Harvard researchers are interested in : they say this new tool is powerful enough to help analyse cultural change. "The words are a product of Google's book-scanning project. The company has converted approximately 15 million books so far into electronic documents. That's about 15 percent of all books ever published. It includes books published in English, Spanish, French, German, Chinese, Russian and Hebrew."

Still... let us not forget it is but a tool :o)
