Various types of STI are available via these collections; you can find research results and science information from the Manhattan Project to the present, including technical reports, patents, scientific data, and software.
- SciTech Connect  contains over sixty-five years of energy-releated citations created and/or collected by OSTI. There are over 2.5 million citations, including citations to 1.4 million journal articles, 364,000 of which have digital object identifiers (DOIs) linking to full-text articles on publishers' websites. SciTech Connect also has over 313,000 full-text DOE sponsored STI reports; most of these are post-1991, but close to 85,000 of the reports were published prior to 1990.
- DOepatents  is the U.S. Department of Energy's central collection of patent information, where research and development intersect with innovation and invention. This collection demonstrates the Department's considerable contribution to scientific progress from the 1940s to today.
- The Energy Science and Technology Software Center (ESTSC) is the centralized software management facility for the U.S. Department of Energy (DOE). A component of the Office of Scientific and Technical Information (OSTI) in Oak Ridge, Tennessee, the ESTSC licenses and distributes scientific and technical (S&T) software developed by DOE contractors, national laboratories, and other facilities. This S&T software is a form of scientific and technical information (STI ) resulting from DOE-funded research and development (R&D).
- The DOE Data Explorer (DDE) provides access to scientific research data - such as computer simulations, numeric data files, figures and plots, interactive maps, multimedia, and scientific images - generated in the course of DOE-sponsored research in various science disciplines.
In addition to STI, you can discover e-prints , read about ongoing federal  and DOE research projects  and amazing accomplishments , and search science conference proceedings  or green energy information , by visiting one of the products below.
