I think this brings up a good point. Think about how much of our information comes to us in digital form, and delivered to us from sources outside of our control.

A good example recently I had a movie removed from my amazon account that I purchased years ago. Granted Amazon refunded the purchase amount – however what happens with they decided something is no longer fit for society.

That information is removed – gone. Unless you downloaded a copy of it.

With everything online – the ideal of burning the library of Alexandria – can be done in a few key strokes.
