Science.govGateway to the best science information from government sources.
Science.gov is a gateway to selected high quality science information for professionals, students and educators, business people and entrepreneurs, and members of the public with an interest in science. It was developed by an interagency working group of 14 scientific and technical information organizations from 10 major US government science agencies (NASA, EPA, NSF, and Departments of Agriculture, Commerce, Defense, Education, Energy, Interior, and Health & Human Services). Science.gov contains reliable information resources selected by the respective agencies as their best science information. Two major types of information are included: selected authoritative science web sites, and databases of technical reports, journal articles, conference proceedings, and other published materials. Up to 10 resources can be searched simultaneously, and nearly 30 of the databases are part of the ?invisible web? ? databases not usually accessible from regular web search engines.
