OSTI has been making government R&D results transparent since 1947. OSTI produces a variety of databases making U.S. DOE scientific and technical information freely accessible to the public. SciTech Connect is replacing the Information Bridge and Energy Citations Database and has a new semantic search interface.  OSTI has also created a number of federated search tools to increase access to scientific and technical information: ScienceAccelerator.gov, Science.gov, and WorldWideScience.org.
