The SOA/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics operated by the Smithsonian Atrophysical Observatory (SAO). It maintains three databases which cover publications in astronomy and astrophysics, physics, and the arXiv e-prints.
INSPIRE is a trusted community hub that helps researchers to share and find accurate scholarly information in high energy physics (HEP). It serves as a one-stop information platform which provides users with high quality, curated content covering the entire corpus of HEP literature, conferences, institutions, journals, researchers, experiments, jobs and data.
The NASA Technical Reports Server provides access to NASA's current and historical technical literature.

Search results include: conference papers, images, journal articles, photos, meeting papers, movies, patents, research reports, and technical videos.
The United States Department of Commerce National Technical Information Service (NTIS) serves as the largest central resource for government-funded scientific, technical, engineering, and business related information available today. Included are citations for millions of publications in hundreds of subject areas.
Physical Review Online Archive, or PROLA provides access to the following: Physical Review Series I and II (1893-1969), Physical Review A - D (1970-2016), Physical Review E (1993-2016), Physical Review Letters (1958-2016), and Reviews of Modern Physics (1929-2016).
At the end of each calendar year, PROLA adds another year of content.
Science.gov is a search engine for government science information and research results. Currently in its fourth generation, Science.gov provides search of more than 50 million pages of science information with just one query, and is a gateway to over 1,800 scientific Web sites.
SpringerLink is an integrated full-text database for journals and books published by Springer. Disciplines covered include: architecture & design, biomedical sciences, business & management, chemistry, earth sciences & geography, economics, education & language, engineering, environmental sciences, food science & nutrition, medicine, philosophy, physics, psychology, public health, and social sciences.
Web of Science (WoS) indexes leading scholarly journals, books, proceedings, and other formats. Its major subject areas include the natural and social sciences and arts and humanities with coverage back to 1900. The heart of WoS is the Web of Science Core Collection, which indexes thousands of scholarly journals by author, author affiliation, and cited reference. In addition to the Core Collection, Web of Science provides access to several regional, subject, and format-specific database.
The suite of video tutorials teach aspects of searching, analyzing results, creating a researcher profile, and more. EndNote Web, the bibliographic management tool, is integrated into WoS.
