No, it's not an abstract, in the sense used by the DOS. It fulfills all the qualifications listed by the DOS.
Futhermore, I think you'll find that more and more states, if not all, are now or will be issuing this type of document in lieu of a photostat of an original certificate in response to a birth certificate request. It saves time in not having to research microfilm or image files, and it saves money for the same reason.
As I said above, I have one, and it's been acceptable for a passport app, and I have no reason to believe it won't be acceptable for anything else that requires proof of birth in the US.
Yes, it’s a computer generated abstract and does not fulfill all qualifications. Since you offered up Connecticut, let’s take a look at Connecticut:
