1) There were comments on my series which culminated in 1940 U.S. Census Comparisons - Summary and Conclusions (posted 23 July 2012):
* Jude said: "I've indexed over 22,000 names on Family Search. Sometimes, I'll be completely wrong on a name, and when I go back to the name on a second pass, I'll suddenly know that what looked like Ophiel is really Pearl. I wish I were perfect at it, but I'm at 98% accuracy, and after about 2,000 names, I got a lot better. I think that everyone who is doing Family Search's indexing, whether LDS or not (I'm not) really, really cares about getting every name right. I know that *I* feel that way. Unfortunately, perfection isn't possible."
* Michael W. McCormick noted: "Thanks for the timely, thorough analysis of these two indexing efforts. At RootsTech an Asian company presented on indexing and I heard Ancestry.com does a subcontracted foreign single pass index. I think they might be using them, but I could be wrong. The RootsTech class was impressive though so I thought they'd do a good job. All things considered for a one pass, probably foreign index, it is really good. I'm glad the community can hopefully get insights from this--whatever those might be."
* Sharon commented: "Thanks for the analysis. I was a bit surprised by how different the results were between the two companies. In time, however, this may change. Ancestry permits corrections to their 1940 census indexing by users; FamilySearch does not. So if it is wrong on FamilySearch, it will stay that way forever. If it is wrong on Ancestry, it might get corrected.
"This makes it even more important for Ancestry users to submit corrections when they do locate an indexing error. You can even add alternate names if it is not truly an indexing error. For example, the census itself may have been wrong, or perhaps only initials were used instead of a full given name. So if you see something in the Ancestry index that can be improved, please submit a correction or alternate name."
"As a FSI indexer and arbitrator – even with several aids at my disposal – it was hard deciphering between the ‘a’ and ‘o’, or ‘e’ and ‘I’. FSI guidelines were to TWYS (type what you see) – not being influenced with the 1930 Census or other sources.
"I know record indexing accuracy is important, but my main excitement will be when I find my family records – with exact spelling or with other filtering aids. I will provide my searching results when Illinois becomes searchable on FamilySearch or Ancestry."
