Think of it this way.
I have a copy of Origin of Species which contains information.
I buy another copy. Do I now have twice as much information? Or 2 copies of the same information?
Depends on your definition of information. What's yours?
I tear a page out of one copy and glue in a page of random numbers. That's a deletion and an insertion. Does that give me more information?
