Two people died. Thousands of documents going back nearly 1100 years were in rubble. Half a million photographs were housed there. Disasters such as the Cologne archive collapse demonstrate why it is important to digitize cultural records. Digital versions help protect and preserve a heritage.
So with thoughts of Cologne, here's a photochrom print circa 1910 of the Eisenbahn Bridge at Cologne from the Library of Congress collection. I haven't restored it yet; maybe someday.
