Excellent ideas from Judy but I have 1 remark. If you wish to look at microfilm in the Law Library at the courthouse, I would make sure that you were going to have access to the reader when you want to use it. I don't know if they would make an appointment to guarantee you a time for use or if someone would happen to walk in 5 minutes before you planned to use it, that they would get the machine & you would be out of luck. If you are just going back to look at tax books, then that would be different, but if you are going to want to look at some estate records (wills, settlements & papers involved, that are on microfilm) that has to be taken in to consideration.
