OSTI MissionTo advance science and sustain
technological creativity by making R&D findings available and useful to
Department of Energy (DOE) researchers and the public
• Making government-sponsored R&D information available via single-query aggregated portals
• Responding to practices of searchers.*
Librarians, researchers and the public Librarians, researchers and the public can access a science page count can access a science page count

*In 2002 OCLC “Perceptions of Library and Information Resources,” 84% of public began search using search engines; only 1% began with online databases.
Integrates 10 key DOE databases that cover a range of R&D results (reports, patents, citations, project summaries, eprints, etc.)
Integrates science information databases and portals from >60 nations
Drills down to selected databases and websites in parallel, then presents ranked search results
Free Aggregator of Multiple Government R&D-related Databases
Integrates databases and websites of 14 U.S. science agencies
• less than 1% overlap with Google • approximately 3.2% overlap with Google Scholar
Science.gov results are uniquely different from Google and Google Scholar results 95.8% of the time
Integrates simple search interface with database functionality & searches in real time:
• over 40 databases of 14 U.S. science agencies• 200 million pages of science information• Thousands of authoritative scientific websites within .gov domain/sponsorship

Key FeaturesIntegrated Search Portal: Single Query of
Science.gov Databases and Websites
Science.gov helps users identify databases for more advanced searching as needed
• Searches 61 science databases and portals sponsored by governments and national institutions in 61 countries
• Covers scientific literature from over three-fourths of the world’s population
• Includes a vast quantity of science (over 400 million pages), providing significant journal coverage as well as a majority of grey literature.
• Current research in multi-lingual translation technologies will enable non-English databases to be searched from the WWS interface
• Proving WWS “deep web” value, recent analysis shows only 3.5% overlap with Google and Google Scholar

Science.gov and WWS Discovery Tools vs. Discipline-Oriented Databases
Science.gov Govt Portal Search
Discipline-Oriented Databases
• Generally have more human input, preparation of data prior to posting
• Have more administrative control (not reliant on underlying databases)
• Presentation of information uses standard fields, standard look and feel, standard query search strings often makes for more comfortable user experience (especially at first)
• Depth of information can be achieved due to discipline-specific nature
• One-stop access to multiple databases targeted for inclusion
• Integrates and organizes huge amount of information
• Provides well-rounded picture of topic to quickly scan environment
• Offers user the ability to drill down to individual database(s)
• Simple searching, yet powerful results: one search box or advanced search specifying fields or databases
• Modules enhance user experience with quantity of information, e.g., clustering, filtering, sorting, menu selections
