OSTI provides access to DOE STI (Scientific & Technicla Information) both unclassified and classified, through a suite of web-based, searchable discovery tools and through other commonly used search engines, offering ever-expanding sources of R&D information to DOE, the research community, and the science-attentive public. OSTI makes 70 years of research results from DOE and its predecessor agencies discoverable. Research results include journal articles/accepted manuscripts and related metadata; technical reports; scientific research datasets and collections; scientific software; patents; conference and workshop papers; books and theses; and multimedia. OSTI.GOV contains nearly 3 million citations, including citations to 1.5 million journal articles, 1 million of which have digital object identifiers (DOIs) linking to full-text articles on publishers' websites. It also has more than 445,000 full-text DOE-funded STI documents. OSTI.GOV is the primary search tool for DOE science, technology, and engineering research and development results and the organizational hub for information about the DOE Office of Scientific and Technical Information. It consolidates OSTI’s home page and our now retired primary search tool SciTech Connect.
