Many times in my journeys I come across Carnegie library buildings. Some times they are still in use as a library but more often than not they have taken on a second life, generally as a museum. Here is an example of a Carnegie library-turned-museum in San Luis Obispo, California. What a great looking structure. What's on display inside? Bicycles! There is a display of various bicycles from the early giant wheel variety to more current racing bikes. See for yourself.
