http://www.google.com/insidesearch/features/search/knowledge.html

Discover answers to questions that you never thought to ask and explore collections and lists. With a carousel at the top of the results page, you can get a more complete picture of what you’re curious about. Explore collections from the Knowledge Graph and browse lists of items, like [popular movies of 2011] or [museums in NYC], that help you research a topic faster and more in depth than before. Language can be ambiguous—do you mean Rio the city, the movie, or the casino? With the Knowledge Graph, Google can understand the difference, helping you more precisely express what you mean as you enter your search. Go under the hood with members of the team who work on this technology. Information from the Knowledge Graph is available on desktop, tablet, and your smartphone. So wherever you search on Google, you’ll find that answers and discovery are at your fingertips. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
