"SciTech Connect is a portal to free, publicly-available DOE-sponsored R&D results including technical reports, bibliographic citations, journal articles, conference papers, books, multimedia and data information. SciTech Connect is a consolidation of two core DOE search engines, the Information Bridge and the Energy Citations Database. SciTech Connect incorporates all of the R&D information from these two products into one search interface. SciTech Connect was developed by the U.S. Department of Energy (DOE) Office of Scientific and Technical Information (OSTI) to increase access to science, technology, and engineering research information from DOE and its predecessor agencies."--FAQ.
