Some of the favorite reading materials in most libraries are mystery and detective books. So it is only appropriate that libraries themselves should be the focus of a few mysteries and maybe a secret or two.
Does a ghost wander the library after hours? The subject of documentaries, investigations, and online camera survelliance the Willard Library in Evansville, Indiana.
Eureka Springs Carnegie Library
Secret tunnels? A mysteries link to the historic Crescent Hotel? This library and the community have been explored by "Underground Eureka" and documented the area but have yet to find such a tunnel. A delightful little urban tale and one which makes me, for one, want to go back to see things for myself.
