"The Department of Energy (DOE) Office of Scientific and Technical Information (OSTI), a unit of the Office of Science, fulfills agency-wide responsibilities to collect, preserve, and disseminate both unclassified and classified scientific and technical information (STI) emanating from DOE-funded research and development (R&D) activities at DOE national laboratories and facilities and at universities and other institutions nationwide." - Publisher's description.

"We provide science about the natural hazards that threaten lives and livelihoods, the water, energy, minerals, and other natural resources we rely on, the health of our ecosystems and environment, and the impacts of climate and land-use change. Our scientists develop new methods and tools to enable timely, relevant, and useful information about the Earth and its processes." - Publisher's description.

The Nuclear Regulatory Commission, formerly the Atomic Energy Commission is responsible for regulating various commercial, industrial, academic, and medical uses of nuclear energy.

For over 200 years, the basic role of the Patent and Trademark Office (PTO) has remained the same: to promote the progress of science and the useful arts by securing for limited times to inventors the exclusive right to their respective discoveries. Patent full-text and full-page image databases are accessible through this web site. Patent grants are full-text since 1976, with full-page images since 1790. Patent applications are available for those published since March 15, 2001.
