Notation/music question:

I have a song (Beatles' It's Only Love) which has a variety of TAB versions -- the original is somewhere up on the high frets, and the one in E that I have refers to B7aug (you know: "My, oh my..."). What the hell is a B7aug? As usual, it also comes with +. The only chord book that comes close has B7+5 (augmented 5th). Is that what a B7 augmented is by default? Or is it a 9th? And then there is something that looks like B+7. Can't be the same, can it? Just a B augmented with a 7th attached (which sounds like it would mean the same in the wash) Is it? Help!!! The specific notes would help a lot.

yours, Peter T.
