Google has confirmed with Search Engine Land that the company is currently testing new a ‘sources’ display inside of Search. As you can see above, the sources section pulls in information, in this case about Rihanna, that has appeared on Wikipedia and various other sources. The section also pulls in song information, in Rihanna’s case.
In most instances while searching on Google you want to find definite information — fast. Google has implemented similar features inside of Search for weather, sports, math calculations, and more. Keep ‘em coming!
