Talk:Indexing Projects - US, Iowa County Births, 1880-1935

I have seen a few batches where there is a real certificate as an overlay and you can see the entry on the register. If there is a difference between the information on the overlay and the register, is the child's info supposed to be indexed twice? And if there is no difference, it is to be indexed only once?

You would first index the overlays then index complete lines. You treat them as separate documents, in other words, you pretend that you don't know what is on the overlay when you index the origianal line, that was ammended. Unless it is a carbon copy, go ahead and index it twice if the overly and the line have the same information, this will let a researcher know that there are two separate documents to view, even though the information may be the same. Hope this answers your question.
