National Institute of Standards and Technology - "The National Institute of Standards and Technology conducts and supports scientific and engineering research in disciplines ranging from chemistry and physics to information technology. NIST provides access to material pertinent to their mission from this website. There are links to NIST scientific and engineering data, standards, databases, laboratories, software, and other NIST information and services." http://www.nist.gov/public_affairs/researchers.htm
Science Accelerator - Science Accelerator "is a portal searching searches vast scientific and technical resources, including R&D results, project descriptions, accomplishments, and more, via resources made available by OSTI. This database was developed by the Office of Scientific and Technical Information (OSTI) within the Department of Energy (DOE) and is available as a free public service." http://www.scienceaccelerator.gov/
Energy Citations Database - The Energy Citations Database (ECD) "provides free access to over 2.3 million science research citations from 1948 through the present, with continued growth through regular updates. There are over 150,000 electronic documents, primarily from 1994 forward, available via the database. ECD includes scientific and technical research results in disciplines of interest to DOE such as chemistry, physics, materials, environmental science, geology, engineering, mathematics, climatology, oceanography, computer science and related disciplines. It includes bibliographic citations to report literature, conference papers, journal articles, books, dissertations, and patents." http://www.osti.gov/energycitations/
DOE Information Bridge - "The DOE Information Bridge provides free public access to full-text documents and bibliographic citations of Department of Energy (DOE) research report literature. Documents are primarily from 1994 forward and were produced by DOE, the DOE contractor community, and/or DOE grantees. Legacy documents are added as they become available in electronic format. The subject areas included are physics, chemistry, materials, biology, environmental sciences, energy technologies, engineering, computer and information science, renewable energy, and other topics of interest related to DOE's mission." http://www.osti.gov/bridge/
DOE Data Explorer (DDE) - DDE contains scientific research data, such as computer simulations, numeric data files, figures and plots, interactive maps, multimedia, and scientific images - generated in the course of DOE-sponsored research in various science disciplines. http://www.osti.gov/dataexplorer/
National Technical Information Service (NTIS) - NTIS is an agency responsible for collecting for government-funded scientific, technical, engineering, and business related since the 1950s. The NTIS database provides citation information for over 3 million publications from 1964 to the present. http://www.ntis.gov/search/index.aspx/
Science.gov - Search engine providing single search access to over 50 million pages of government science and reseach results. Many results are available in full text. Site is maintained by the Science.gov Alliance, a group of STI government agencies. http://science.gov
