I’ve been working with FamilySearch digital images online and my conclusion is this: if I want to do research on material in the film beyond a quick check of one item, I will order the film.
It is cumbersome to go back and forth; I have some trouble with pages not loading, especially after I’ve viewed several pages. If I happen to move my fingers wrong on the touch pad the screen moves. Some pages aren’t in the correct order.
In the end, I tend to find what I want and not try to get much more information from the source — which is poor research technique.
I used to think microfilm was an unfriendly media, but to tell the truth, I think I prefer it to digital images on a viewer.
This problem is not limited to FamilySearch. Some online viewers are better than others, but on the whole, I can do more with the information if I have the film.
