However, my children's ancestor attended First Lutheran Church in Galesburg, Illinois, and I'm pretty certain those records are available on microfilm. I used them years ago and the ability to have them online will be pretty nice.
You can learn more about the collection on the Evangelical Lutheran Church in America's website. There is not an inventory online, but the page indicates:
These [films] are primarily from The American Lutheran Church portion of the predecessor bodies, but also include a number of Swedish-American Lutheran microfilms.
I've emailed the archives to see if they have films for churches in which I have an interest.
The ELCA site has an interesting section on Lutheran Churches in Chicago.
I think I'm more excited about this than I was the 1940 census release (grin!).
