I've noticed a difference in the last few years. Our small-town library is largely unchanged. It's still a quiet place were whispering seems natural, but the main branch in the city is quite different. They have added a coffee shop, computers where people access the internet and even televisions where people can pop in a movie. Patrons sit at tables and carry on conversations in a normal speaking voices, and one day I got to listen to a very interesting, one-sided cell-phone call. I suppose you could say I was eavesdropping, but he spoke loud enough I couldn't help but over-hear, and of course my imagination started filling in the other side of the story. It will probably make it into one of my books someday.
It doesn't really bother me, but I do find it interesting. I see fewer people just sitting and reading a book than I used to. Now everyone is plugged in somehow and it has become more of a social gathering place. Personally, I prefer my little-small town library where the librarians greet me by name and often put books aside if they think I'd like them. And overall, it is still a quiet place where I can escape and be surrounded by the printed word. As far as I'm concerned, it doesn't get much better than that.
