About Science.gov (Source: http://www.science.gov/about.html)
Science.gov provides public access and a unified search of the governmentâ€™s vast stores of scientific and technical information. Science.gov is an interagency initiative of 17 U.S. government science organizations within 12 Federal agencies.
Two major types of information are included â€” selected authoritative science Web sites and often hard-to-access scientific databases (specific content varies by database). This gateway to government science information allows searches across 30 databases and more than 1,700 science Web sites. Science.gov currently accesses over 47 million pages of government science information.
