Surprising Book Facts

I'm working on my 2015 Book List, and I came across this image on Facebook.  I'm not sure where this information came from or even if it's true - but if it is, it is very surprising to me.  Or at least very hard to believe or understand.  There are so many books available - books on every conceivable subject full of stories about everything under the sun.  You'd think everyone would be able to find something of interest.

But, apparently, they aren't even looking.

Just sad.
