It's all about one's point of view. I'm assuming you're out of college and don't care about the cost of tuition. A college student couldn't care less about public libraries because...

   1. Colleges have their own libraries
   2. Cost of tuition is way more important to him/her

From my point of view, it looks like this:

How much information is in a library that can't be found elsewhere online? Now what about the other way around, though. How well can advanced college topics be taught with a book from a library?
