You’re familiar with Google, of course – as are the faculty and students that you work with. You probably know of one or two others – Bing, perhaps.

But have you ever heard of DuckDuckGo or Blekko? Check out this interesting rundown of a few current (non-Google) search engines – how they work and what they do best – from Lifehacker.
