What is STIP?

The U.S. Department of Energy (DOE) Scientific and Technical Information Program (STIP) is a collaboration from across the DOE complex working to ensure that the results of DOE-funded research and development (R&D) and other science and technology activities are identified, disseminated, and preserved.

Why We're Here

STIP members, led by the DOE Office of Scientific and Technical Information (OSTI), work together to increase the availability and transparency of various types of scientific and technical information (STI).  This site provides background, guidance, and more to support the management and preservation of DOE-funded R&D results now and in the future.
