This is the second largest genealogy collection in the US ant it is online searchable. The largest is LDS in Salt Lake.
The LDS database has literally never given me anything beyond what I already knew, and of the stuff that was on there, much of it was dead wrong. It can be useful for those starting out with a tabula rasa, but only in that it can point them to what they need to research and perhaps where.
Thanks for that other one, I’m bookmarking it.
