History

Science.gov 1.0 was launched in December 2002, providing for the first time wide public access and a unified search of the government's stores of scientific and technical information. Science.gov is an interagency initiative of 18 U.S. government science organizations within 14 Federal agencies. These agencies form the voluntary Science.gov Alliance. In May 2004, Version 2.0 was launched, introducing real-time relevancy ranking to government science retrieval. This technology, funded by the Department of Energy, helps users sort through the government's research and return results relevant to individual needs. An advanced search capability and other enhancements were added.

A free "Alert" service was released in February 2005, allowing users to receive e-mail alerts about current science developments in their areas of interest. Up to 25 relevant results from selected information sources can be delivered. Results are displayed in the Alert email and in a personalized Alert Archive, which stores six weeks of alerts results. In the Archive, past activity can be reviewed and Alert profiles edited. Launched in November 2005, Version 3.0 provided more refined search queries of federal science
