A new (?) NY Times research tool

This may not be new, but I just noticed it and thought it was kind of cool. You can doubleclick on any word in a NY Times story and a new window opens with information about that word from the American Heritage dictionary, an encyclopedia published by Columbia Univ., and the Dictionary of Cultural Literacy. Doubleclick the word manslaughter in the NYC strip club slayings story, and an explanation of manslaughter pops up. Doubleclick "Eastwood" in the Iwo Jima story, and an entry for Clint Eastwood pops up. Click on Salt Lake City, and you get info about the city as well as a weather report. None of the words are hyperlinked. I get the sense that it is something they're working on ... click on "Kennedy" in "Kennedy International Airport" and you just get info on President Kennedy. Neat nonetheless.

 

Sounds like it could be a useful tool.
