Put together by 18 U.S. government science organi-zations spanning 14 Federal Agencies, Science.gov is a website providing access to government science information and research results. It allows users to simultaneously search over 42 scientific databases and 200 million science information web-pages. The site was originally launched in 2002 and has now moved on to version 5.0. The intended audience includes science professionals, students and teachers, and the business community. Further information about the site and its history can be found here.
Recently, science.gov added an image search feature to its page. The link to "Image Search" can be found on the bottom right of the home page, under the heading "Special Collections," and lets users quickly find science images including plant and animal, weather and space, earth and sun, and other images. The image search currently searches three databases simultaneously: The National Biological Information Infrastructure (NBII) Library of Images from the Environment (LIFE), The National Aeronautics and Space Administration (NASA) Image eXchange (NIX), and The National Oceanic and Atmospheric Administration (NOAA) Photo Library. Other image databases will be added in the future. This credible image collection is a very handy resource that can be used for free by anyone with an internet connection.
