Book excerpt: Drawing from the nearly half a million photographs and documents comprising the Historic American Buildings Survey held in the US Library of Congress, this book constructs a fictional ?one-way road trip? across the United States, weaving north and south across the Mason-Dixon line while tacking west. In A Field Measure Survey of American Architecture, Jeffrey Ladd uses the HABS archive as a surrogate in order to manifest a portrait of his former country at a moment when its democracy seems imperiled.00Inspired equally by the social documentary work of Walker Evans and the architectural interventions of Gordon Matta-Clark and others, Ladd embraces the muteness of photographs to create an ambiguous space where the sculptural, political, forensic, and fictional coalesce within a landscape of both beauty and fragility. What initially appears to be a single voice is revealed to belong to dozens of makers; what seems a description of the distant past is revealed to be closer to the present than expected. A Field Measure Survey sheds light not only on this remarkable archive but on the proliferate meanings that can be shaped from its images.
