Don't overlook college campuses in your tour d'horizon of local resources. I'm not thinking of just the archives and special collections for the moment (although I did blog one set here), but the humble catalog itself. For instance, Ball State University in Muncie has possessed itself of several series of microfilmed records from Delaware County, Indiana: marriage, property, probate, and circuit court order books. And that library is usually open until 3 am, which is more than you can say for the off-campus variety! These goodies are collectively numbered 2303 in Bracken Library's microfilm numbering system.
