Realizing it's just a spec microbe in the time continuum, the 30-year period I've owned my first CD 
purchases has done nothing audible to them. I just popped one in the player, back to 1984. Really 
bad made-in-Germany remaster of "Van Halen II". I think the first US-made discs were 1985 or 1986, 
Sony from Terre Haute. I think Philips-DuPont Optical in North Carolina got going by late 1986.

LOC should test what fingerprints do to the plastic, even if they are cleaned off months or years 
after being gooped on. I've cleaned fingerprints off library CDs and there were still little 
off-color areas remaining, I assume the oil un-cleared the plastic somehow (yep, I sure didn't take 
any chemistry classes so I have no idea about the correct terminology).
