DCist: Transportation Department Publishes Thousands Of Historic Photographs. “When Kathleen Crabb first started working at the District Department of Transportation’s library, she realized that the institution was sitting on a trove of historic images. But first they needed to be excavated, after decades of being thrown in boxes with little regard for organization, preservation, or reference. For the past two years, Crabb has been physically sorting through the materials and getting them online. The result, unveiled last week, is a new digital archive called DDOT Back In Time.” It’s still in progress.
