Do not underestimate the LDS church. I'll never be Mormon, but this is something they take very seriously and put a lot of resources into and I'd bet on them to be the best in the world in the field.
If you are referring to me......I wasn't referring the the LDS, my apologies, I think it likely has the most extensive collection that probably works for alot of people.
I use other sources is all, and they are available for research.
