Ancestry.com recently announced the database U.S., Consular Registration Applications, 1916-1925
on their site. I can't tell if this is totally new or something that was updated--Ancestry.com does make that a little bit difficult to tell.
At any rate, the images are nice and there is great information on the forms if you are lucky enough to find one on a relative. This image is part of the application for George W. Drollette, brother of my wife's great-great-grandmother. Lots of good detail on here. We've written about George's many passports in Casefile Clues.
