At Scanning Depot, we have been busy scanning 16mm roll film cartridges, 35mm microfiche jackets, and 16mm school records. We are also working on a government bid that requires us to invest time and effort to put together for them.
In our case, it looks like the first microfilm trend to hit (Obama bailout money) was school records. We can only comment from our own experience and others may feel differently, but from our stand point, we have seen a trend of microfilm school records converted to digital format.
