Climate modeling is an active field of research, and study of the field depends on large data sets. The Climate Data Online website allows users to search for a number of measurements and other historical information, including record weather events. Users can also search for storm information and results from various climate models.

Another large database is the U.S. Copyright Office's copyright database. Because records prior to 1978 were stored in analog format, only information from 1978 adn later is available in a searchable format. However, the Internet archive hosts scans of work from 1977 and earlier.

The Internet Movie Database began in the 1990s as an effort to catalog movies, actors and other related information and has grown into the world's largest movie-related database.
