Our Collection

The DDOT Library houses the agency’s general, reference, map, serial, periodical, multimedia, and historical collections, as well as a small archival collection. The collection includes studies, reports, and plans from the various administrations across DDOT and the District government, as well as manuals, specifications, and other publications from ITE, AASHTO, TRB, USDOT and FHWA.

About the DDOT Library

The purposes of the DDOT library are to preserve and create access to District transportation history and to provide a central source of current information, which includes maintaining the current collection as well as acquiring new items according to patron need and keeping track of new and engaging topics in the transportation field. The Library's primary focus is DDOT employees, but also serves the rest of DC government as well as the federal government, consultants, researchers, and the public. If you are not a DDOT employee and wish to visit the Library just call or email the librarian and we will be glad to assist you!

History of the Library

The current District Department of Transportation Library was founded in 2011. In years past there was a small collection managed by a part-time librarian, but the collection was then abandoned until a historian was hired in 2005. After the move to 55 M Street, over three-hundred boxes of donations were made. Starting the library has allowed all employees to have a central location in which to look for needed materials and conduct research for studies, current and future DC transportation projects and scholarly studies.
