When Darlene Weaver of Circleville, Ohio, became volunteer director of the Pickaway County Historical Genealogy Library in 1996, the library's few books and two file drawers occupied two rooms of an old house. Twelve years later, neatly filed and indexed county and state records filled all 14 rooms, six closets and a bathroom, necessitating a spring 2008 move to spacious new digs.

"[Weaver] will tell you her fellow volunteers are the reason the library is such a success, which in part is true, but volunteers know it's Darlene who has the vision," says nominator Cinda Justice of Williamsport, Ohio.
