Department of Transportation's National Transportation Library joins Science.gov

The United States Department of Transportation (DOT) National Transportation Library (NTL) joined Science.gov in 2009. Science.gov searches over 36 databases and 1,850 selected websites, offering 200 million pages of authoritative U.S. government science information, including research and development results.

The DOT NTL Integrated Search has been added to both the basic search and the advanced search in Science.gov. The major subject areas of this source are highway and transportation engineering, statistics, planning, policies, and research.

Included in the NTL Integrated Search are:

TRIS Online, which includes the disciplines of planning, finance, design and construction, materials, environmental issues, safety and human factors and operations for the modes of highways, transit, railroads, maritime and aviation. TRIS focuses on transportation research. NTL Digital Repository, primarily technical, research, and policy documents provided by federal, state, local, tribal, and other government agencies.

Science.gov is hosted by the U. S. Department of Energy Office of Scientific and Technical Information (OSTI), within the Office of Science.
