From Whence These New York Marriages?

Ancestry.com recently added (or updated, it's always difficult to determine which) their "New York Marriage Notices, 1800-55," which apparently was taken from Early Marriages From Newspapers Published in Central New York. n.p.: Pipe Creek Publications, 1992. .

That's all fine and good, but I was unable to determine if there was a listing indicating what newspaper the items were from. The one shown in the illustration here has a code of "SD." Others had different codes and, in my quick survey of the site, I could not find a listing of the abbreviations.

The description, shown below, was not helpful:

About New York Marriage Notices, 1800-55

Among the most important states in the young union, New York was home to over a million people in the early 1800s. This database is a collection of marriage notices published in newspapers around the state in the first half the nineteenth century. Each record contains the names of bride and groom, marriage date, marriage location, residence, and newspaper in which the notice appeared. Additional information is provided which in many cases includes names of witnesses, relatives, and parents. For those seeking ancestors from New York after 1800, this can be an informative database.

Frankly that description sounds like boilerplate text to me and could apply to a variety of items.

Hopefully someone will indicate that I've overlooked the list of abbreviations. It would have been nice for them to have been included and I'm hoping they are buried on the Ancestry.com site and I simply have not found them. Having the abbreviations in the description would have been helpful.
