Libraries are by far one of the most valuable institutions we have today. It's essentially free information, the biggest source outside the internet. With inter-library lending systems, you can get nearly any published book you can think of. It's not just fiction and novels, it's non-fiction, biographies, autobiographies, newspaper articles, books on politics, crime, law, botany, philosophy, anything you want, from Plato to Bill Bryson.
And it's all free, no cost, except depending on how your state or town pays for them. That's up each one individually whether its taxes or what, but there's no fees or dues for all that service. Unless you return a library book late.
I wouldn't advocate closing them down in favor of the internet or anything else.
My daughter and I go to our public library at least twice a week. We get movies, CD's and of course books, for FREE! If we are late turning something in, and I have to pay a fine, I never gripe, because I know my money goes to a good cause, and it's still the best deal in town.
She asked me the other day, "Mom, why would someone want a Kindle? Why wouldn't they just go to the library and get the book there?"
There is nothing better than turning the pages on a book, even the smell of them,,,,I have had a love affair with books since I could read, and I will fight tooth and nail to keep our libraries open.
