In the excellent xkcd comic embedded above, you can see the unique problems future generations will face when they decide to burn books.

Here’s more about Randall Munroe, the creator of the comic series: “I’m a CNU graduate with a degree in physics. Before starting xkcd, I worked on robots at NASA’s Langley Research Center in Virginia. As of June 2007 I live in Massachusetts. In my spare time I climb things, open strange doors, and go to goth clubs dressed as a frat guy so I can stand around and look terribly uncomfortable. At frat parties I do the same thing, but the other way around.” (Via Blake Gernstetter)
