Zed sez “Irradiating the mail to the Library of Congress is destroying submissions, including, in the cheap irony dept., irreplaceable taped interviews of reactions to 9/11.”
Photographs of potentially historic value are fused onto cover sheets where the caption ink has melted off, making them impossible to decipher or preserve. A videotape of an oral history interview conducted for a special project to capture the memories of war veterans is not playable.
(Thanks, Zed!)
