"Archives are the foundation of historical research. Without access to primary material—be it documents, photographs, financial statements, engineering or test reports—historians lack the building blocks necessary to write the chronicles that inform our understanding of the past and illuminate the future. To their credit, America’s automakers have gone to great lengths and expense to preserve and protect the historical documents which chronicle and define their existence. Until recently. As Chrysler and GM plunged into bankruptcy, they turned their back on their own heritage and destroyed a priceless part of our collective past."
