Hi,
I am assuming you are talking about microfiche and not microfilm readers, correct? Some of the above responses make me wonder if there are documents on still microfiche. The Family History Centers had some of their information on microfiche which are the little pieces of about 4 X6 inches film/negatives. Microfilm are on rolls and are still being used. When attending the Family History Center there wasn't much on microfiche. Now that we are in the digital age, I wonder how much can still be found anywhere on microfiche.
