Disagree, based on personal experience. For example, my original Birth Certificate had incorrect spellings on entries, and had to be legally changed two times before the officials typed it in correctly. I have discovered places on the internet (and even in some genealogical research instances in my own family) where folks have inquired into the original birth certificate and ignorantly shared info from same; undoubtedly, they did not know or think to inquire if there were copies of additional changes. When I obtained a copy of my own records, I was able to get all three copies, but do not know why previous researchers did not. One can cite a "Original Birth Certificate" as a source reference; still, that does not necessarily guarantee complete accuracy.
