From The Verge:
Dataset Search launched in September 2018, with Google hoping to slowly unify the fragmented world of online, open-access data. Although many institutions like universities, governments, and labs publish data online, it’s often difficult to find using traditional search.
New features added to Dataset Search include the ability to filter data by type (tables, images, text, etc), whether it’s free to use, and the geographic areas it covers. The engine is also now available to use on mobile and has expanded dataset descriptions.
