Are you using FamilySearch in your research? If not, you are missing out. They are constantly adding records to their site. I was delighted to find recently that digitized marriage records from Webster County, Kentucky are now available. They aren't complete, but I found a number I needed in the 1870s and 1880s. FamilySearch is a free site and has a nice variety of records.
