Access to Science Information Expands with Science.gov 5.0 Launch

200 Million Pages of U.S. Government Science Resources Now Available on the Internet

The latest version of Science.gov—Science.gov 5.0—was launched Sept. 15th, allowing users to search additional collections of valuable science resources; more easily target their searches; and readily find links to information on a variety of science topics. Science.gov is a free, integrated single-search gateway to reliable science and technology information from 17 organizations within 13 federal science agencies.

Science.gov 5.0 improves upon the previous version, Science.gov 4.0, by offering seven new databases and portals which allow researchers access to over 200 million pages of scientific information. New information available includes thousands of patents resulting from U.S. Department of Energy (DOE) research and development(DOepatents); documents and bibliographic citations of DOE accomplishments (DOE R&D Accomplishments Database); millions of electronic scientific documents from around the world known as e-prints (Eprint Network); and comprehensive and peer-reviewed toxicology data for thousands of chemicals (HSDB Hazardous Substances Databank) as well as more than 3 million references to worldwide literature on the adverse effects of chemicals on living organisms (TOXLINE Toxicology Bibliographic Information).  New information also includes a digital archive of biomedical and life sciences journal literature (PubMed Central) and cancer-related information of all kinds for all audiences (Cancer.gov), including support and treatment resources for patients, comprehensive descriptions of research programs and clinical trials for healthcare professionals and the general public, and funding opportunities for researchers.

Another key feature of Science.gov 5.0 is a “clustering” tool which helps target searches by grouping results by subtopics or dates. This technology was recently developed through a DOE Small Business Innovation Research (SBIR) Program award.

In addition to quadrupling the amount of searchable content and enhancing the search technology, Science.gov 5.0 now provides links to related EurekAlert! Science News and Wikipedia, and provides the capability to easily download research results into personal files or citation software.

Science.gov is hosted by DOE’s Office of Scientific and Technical Information (OSTI), within DOE’s Office of Science.  In addition to DOE, Science.gov is supported by contributing members of the Science.gov Alliance, including the Departments of Agriculture, Commerce, Defense, Education, Health and Human Services, and the Interior, the Environmental Protection Agency, the Government Printing Office, the Library of Congress, the National Aeronautics and Space Administration and the National Science Foundation, with support from the National Archives and Records Administration.

 San Francisco – The latest version of Science.gov ( http://www.science.gov ) , launched today, deploys “DeepRank” which allows search and relevancy ranking across full text of documents, when full text is available. In addition, Science.gov 4.0 adds a “refine results” option to narrow returns within a search, as well as an “email results” feature so that individuals may email important science information to themselves, friends and family, or colleagues. Version 4.0 offers more ways to view search results: by title, author or date, as well as by relevancy rank or source, as in earlier versions. “Once again, Science.gov has brought new features and new technology to the forefront for those who need science information quickly,” said Eleanor Frierson, Deputy Director, National Agricultural Library and co-chair of the Science.gov Alliance. “You get a lot of search with just one query, and your results are more relevant than ever.”Tom Lahr, Deputy Associate Chief Biologist for Information, U.S. Geological Survey, and co-chair of the Science.gov Alliance, noted that Version 4.0 will help citizens find the science information they need. “Already, Science.gov searches authoritative science information from 30 federal scientific databases and more than 1,800 science Web sites,” said Lahr. “Now DeepRank, a more sophisticated ranking tool, will help return even more targeted results from these resources.”At Science.gov, a single query can be launched across more than 50 million pages of science information and research results. Science.gov allows users to search the surface Web as well as the deep Web, where traditional search engines typically cannot go. The information is free and no registration is required.

Hosted by the DOE Office of Scientific and Technical Information (OSTI, htttp://www.osti.gov ), Science.gov is the gateway to reliable science and technology information from 16 organizations within 12 federal science agencies.

Science.gov is made possible by members of the Science.gov Alliance: the Departments of Agriculture, Commerce, Defense, Education, Energy, Health and Human Services, and the Interior, the Environmental Protection Agency, the Government Printing Office, the National Aeronautics and Space Administration and the National Science Foundation, with support from the National Archives and Records Administration.

Science.gov is supported by CENDI (www.cendi.gov) an interagency working group of senior scientific and technical information managers from 12 U.S. federal agencies.
