Randy,
The National Archives service records are available on microfilm in several places. In Kentucky, they have the microfilm at the State Library & Archives in Frankfort, and also in the public library in Louisville. (I think there is also a set in Eastern KY, maybe also in Lexington, not sure).
Trouble with the microfilm copies is that they are often unclear, under/over-exposed, etc. The originals in the NA make much better copies.
