Leland Meitzler has published this excellent summary of the U.S. marriage records now up at FamilySearch.org. in his Family Roots Publishing Genealogy Newsline, vol. 1, no. 3 from 2 Feb 2011. Leland says:

FamilySearch.org has posted numerous marriage databases for the United States. Following are links to 53 databases with records for 43 states that you may find of interest. Due to privacy laws, recent records may not be displayed. The year range represents most of the records, while a few records may be earlier or later. In most cases, the records may be researched using microfilm found at the Family History Library and Family History Centers. Note that in a number of cases I have stated that the number of records was AFTER a specific date. I did this when I found that
more records were within the database than I found listed with that date. I’m guessing that this occurs when records are added, but the Collection List Page itself doesn’t get updated.

I’d add that when you see two collections for one state, the second is usually marriage records from the various counties. And I added the hyperlinks.
