Libraries also have other programs to help the community. Mine has places to help people from other countries (like Mexico for example) improve on their English and when I was a kid I took part in summer reading programs and field trips that they sponsored as a way of stimulating Children's minds. Plus for the very young there is story time at the library. As for the way libraries are organized it's done that way so you don't have to go looking all over the entire place to find one book. Fiction in one area and non-fiction in another. Fiction divided by Genre and author and Non-fiction by topic and author name. Without the Dewey Decimal System no one would be able to find anything save by pure luck. I always loved going to the library as a kid. I got my first library card at age 3 and have had one since.
