Google Dataset Search

Dataset Search is a search engine for datasets.

With a simple keyword search, users can discover datasets hosted in thousands of repositories across the Web.

The mission of Dataset Search, in addition to making datasets universally accessible and useful, is to:

Create a data sharing ecosystem that encourages data publishers to follow best practices for storing and publishing data. Give scientists a way to show the impact of their work through citations to the datasets they have produced. The more repositories that describe their datasets with schema.org or similar standards, the more complete and varied results users will be able to find in Dataset Search.
