Legal & Ethical Questions in the PC Audio Age

So, really, you shouldn't even give them away if you've made a perfect copy.

Great discussion. I am persuaded that I should box up the ripped CDs and hang onto them -- for forever, I suppose.

I now regret ripping a CD a friend loaned me recently, so I went looking for it online. Appears to be out of print, but I found a bunch of them from Amazon affiliated sellers. When a CD is out of print, I will often buy it used on Amazon. But this time, I bought the one that was identified as "New," because this discussion makes me wonder to what extent I'm being complicit in unethical behavior when I buy a used CD. Depends: some used CDs are ones people no longer wanted. But, increasingly, they will be ones that someone ripped a copy of and then sold.

Let me give this thread a bump. The topic must surely be heating up. Can anyone point me to authoritative writings on the subject?
