A while ago there was a CBS Sunday Morning a piece about a museum in Europe that knows how to keep children interested while the parents are touring the museum. In each room of the museum a Lego person is hidden somewhere in the room and children must look carefully around to find it. It is sort of a scavenger hunt for children; while this is occurring the parents have time to look at the art work.
I liked this idea because it allows the children to be actively involved in the museum while the adults move slowly through. Think about this occurring in your library. We could have scavenger hunt handouts for various ages that allow the users to discover all the library has to offer. We might adopt the Lego people idea but what about the various genres on our shelves, the services the library offers or maybe even include the librarians on duty that day. This could be a good way to help our new users familiarize themselves with what a modern library is all about.
