"The National Biological Information Infrastructure (NBII) is a broad, collaborative program to provide increased access to data and information on the nation's biological resources. The NBII links diverse, high-quality biological databases, information products, and analytical tools maintained by NBII partners and other contributors in government agencies, academic institutions, non-government organizations, and private industry. NBII partners and collaborators also work on new standards, tools, and technologies that make it easier to find, integrate, and apply biological resources information. Resource managers, scientists, educators, and the general public use the NBII to answer a wide range of questions related to the management, use, or conservation of this nation's biological resources.
The NBII Program is managed by the U.S. Geological Survey's Biological Informatics Office." from web site
"The Science Accelerator empowers you to search, via a single query, important information resources of the U.S. Department of Energy's (DOE's) scientific and technical information. These resources contain the results of DOE research and development (R&D) projects and programs, descriptions of R&D projects under way or recently completed, major R&D accomplishments, and recent research of interest to DOE. The Science Accelerator can be used to search:
- Electronic full-text research reports (including DOE scientific and technical information)
- Energy citations (millions of them, going back to the Manhattan Project era)
- Ongoing research project summaries (what's happening right now in DOE science research)
- Wonderful DOE accomplishments in science
- E-prints (journal article pre-publication drafts, scholarly papers, and more)
- Proceedings and papers from science conferences
- More resources"
