They have a lot, and you can order it for use in the local LDS center in your area. May not be terribly convenient, but they will have resources.
I'm make sure you've thoroughly researched the more readily available resources first, though. It takes a long time to read through a reel of microfilm, and you'll be more productive the more you know.
