"The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 13 million records covering publications in Astronomy and Astrophysics, Physics, and the arXiv e-prints."

"The Interactions.org website is designed to serve as [a] central resource for information about particle physics, including press releases, articles, news, event listings and images."

The Physical Measurement Laboratory "develops and disseminates national standards" in the field of physics.

"The American Physical Society represents some 48,000 physicists, and most of our work centers on scientific meetings and publications-the primary ways that physicists communicate with each other. With PhysicsCentral, we communicate the excitement and importance of physics to everyone."

"Physics World helps scientists working in academic and industrial research stay up to date with the latest breakthroughs in physics and interdisciplinary science."

"Science.gov searches over 60 databases and over 2,200 scientific websites to provide users with access to more than 200 million pages of authoritative federal science information including research and development results."

"The SPDF is a project of the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF consists of web-based services for survey and high resolution data and trajectories."
