Documentary Editing

I am preparing to edit my first documentary- taking a few days off from work so I can have a long weekend.

However I have erred a little on the side of overambition in this case; shooting over 50 hours of footage for what I intend to be a 1 hour piece, or at most 90 minutes.

So how do I sift through all these interviews? The action parts are easy to edit; I can watch them at ten times the speed and mark them and sample in big batches. But the interviews? I am going to have to take notes on all of them and then fit them into my outline.
