My public library is cute, but it needs to be bigger.
If I had my way, it would be the biggest building in town. Inside would be broken into sections.
Kids': Lots of picture and small chapter books. There would be little computer desks with Magic School Bus games and such. There would be pinata-shaped chairs for sitting and playing upon. There would not be a fussy old lady telling the children to hush, but a nice lady who is willing to read and help. There would be a little "jungle" in there, because that's fun.
That section between kids' and teens': Lot's of fantasy books like Harry Potter and The Chronicles or Narnia. At this point, influencing imagination and character is more important than high-brow literature What did the phrase "high-brow" even come from, I wonder.), so there would be Eragon and other things. Roald Dahl is a given. There would be beanbag chairs and big high stools.
Teens': I'm not sure which books I would put here. I think that I would put it conveniently between the second section and adult so that no one would feel restricted to one section, depending on their reading interests. I know that I like to wander between the two sections, and I hate feeling out of place in the library.
Adults': I think that I'd have a huge wall of classics, a huge wall of popular modern books, and a huge wall of little-known treasures. Here, the bookshelves would reach from floor to ceiling, and I'd have some of those neat sliding ladders. Lots of big cushy velvet chairs and couches in a lounge area; people would be allowed to sit how they want. There would be music playing everywhere, but I know some people can only read in silence, so they could have Bose headphones if they wanted. (There might even be an open bar of sorts-- there is at my library now.)
In my library, you would be allowed to talk and make a mess if you wanted, as long as you didn't damage or disrupt anything or anyone. It would be comfortably warm, messy, and loud, but not too much. Everyone could check out as many books as they wanted, I would always have the books they wanted, and nobody would be afraid to ask for help. It would be open at all hours, except for some holidays.
It would be a great library, if you ask me.
