“This is by far the best interactive display for the evolution of the earth that I have found on the internet. It creates awe and wonder along with holding a real value to linking concepts in so many areas.”

Image Search comes to Science.gov

“Science.gov introduces Image Search link – 21 Dec 2010

Science.gov, a gateway to government science information provided by US Government science agencies, has introduced an Image Search link under Special Collections to enable users to quickly find science images, including animal and plant, weather and space, and earth and sun images and more. The information is free and no registration is required.

To begin with, three databases are being searched from one search box. These include: 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 Photo Library. More image databases will be added in the coming months.

In addition to the image search, Science.gov has undergone significant software upgrade for quicker performance. It has included both the Federal Register and Code of Federal Regulations in the basic search and also provides an author cluster on the results page. The alerts service has also been upgraded so that users can manage their Science.gov alerts directly from their alerts email and get daily alerts rather than weekly.

Science.gov is hosted by the Department of Energy Office of Scientific and Technical Information, within the Office of Science, and is supported by CENDI, an interagency working group of senior scientific and technical information managers. Currently in its fifth generation, Science.gov provides a search of over 42 scientific databases and 200 million pages of science information with just one query.”
