The National Transportation Library operates under the Bureau of Transportation Statistics within the United States Department of Transportation. It collects, catalogs, and provides open access to technical reports, statistical data, and policy documents related to all modes of transit and freight. Engineers and planners rely on its digital archives for historical safety data and infrastructure research.
