> There's also the issue that in this case internet archive had moved away from distributing copyrighted material on a strict 1:1 basis with a corresponding physical copy so this particular case was more complex than the lending of personal property.

The judge ruled that this was irrelevant though, which was really stupid. Buying 1 copy should mean that you have one copy to lend out through physical or digital means. It shouldn't matter what form it was in when you bought it.
