Now you can search for data sets from the comfort of Google. The company recently launched Google Dataset Search. This builds on their acquisition of Kaggle in 2017, as another service for data scientists. It will be interesting to watch this space in the future to see if datasets go the route of academic papers and receive citations, as suggested by Linear Digressions, or does a marketplace develop for datasets, where data is anonymized, time bound, etc? An open market in which supply and demand set the price of a dataset could expand the market from mostly hedge funds and PE shops that are the primary buyers of datasets today, to small businesses and developers.
