What happened to the library?

Walking past the city library today I realised I haven't visited a library since I was a student. I miss the library! I remember going to the library as a child, leaving with a big pile of books fully prepared for the holidays in case of rainy summer days. Today the library has been replaced by paperbacks and audio books. I'm wondering, what does the library look like these days? And do you have to be a student or accompanied by a child to feel you belong?
