America's post-industrial cities have been photographed over the past 40 years - often repeatedly, as "time-lapse" sequences - by Camilo José Vergara. These documentary and artistic images are now archived at the Library of Congress' Prints & Photographs Division, with 5,000 of the 10,000 photographs available online.
Vergara's work can be seen now, through January 11, at the Taubman College's Liberty Gallery in the exhibition "Detroit is No Dry Bones: the Eternal City of the Industrial Age"
From the photographer's statement on the Library of Congress site:
"I see photography as a medium that spurs continuous inquiry and thus leads to greater understanding of the spirit of a place. I think of my images as bricks that, when placed in context with each other, reveal shapes and meanings within these often neglected urban communities. Through photography, I have become a builder of virtual cities.
My hope is that my long-term records will become part of our collective urban memory."
