Sorry for the long silence. I was working on some data that was missing. It appeared that I didn't have a spreadsheet for ED 38 for the year 1930. So I indexed it myself, proving that the indexers I have on the project, Eriall Steiner and Karen King do a much better job than I.
I have updated squares 507, 509, 519, 520, 521, 550, and 551. 521 to 551 have 1940 added to them. I also noticed in these updates that data for 550 for the year 1910 looks a little slim. I know more people lived there, I just have to get or find the data for them.
If you are using this data please drop me a line to tell me how, I'm curious to know.
Thanks.
