If its a daily paper, isn't 50 years worth going to generate a monster stack of papers 400ft High?
I am pretty sure any such archive has be visited already by Obama’s plumbers and the incriminating original paper stolen and burned. “sorry that issue is lost...”
Unless a private individual got there first, and put it away in a safe place.
Once the volumes are bound, they take up less room than you might think. They can be shelved, much like books. In the case of plumbers cleaning out any incriminating archives, one doesn’t know what they don’t know ... meaning they might have missed an archive they simply didn’t know existed. The devil is in the details, and investigators are often good at finding such overlooked details. I’m sure the forgers were hoping that forged microfilm would be sufficient to stop skeptics from looking any deeper.
