How do you keep a library quiet?

One of the best ways to keep a library from becoming a noisy or rowdy space is to catch and stop problems before they get a chance to get out of hand. Try to act proactively. If you see a group of kids starting to play around, try talking to them in a friendly manner and simply remind them that they need to try to be quiet while inside the library but they can talk and play all they want outside. If you're a librarian, you could hold an impromptu story time for a group of kids if it seems like they'll be a disruption. For adults, you can simply remind them of the library's rules. Save an aggressive "SHHH" as a last resort!
