"Husband-Coached Childbirth"--I thought this book would be SUPER granola-crunchy-hippie. And in some ways it is. But it's also the best description I've ever seen of the different phases of labor and what both the mother and father can do to make each phase easier. He's an advocate of drug-free childbirth, but even if that's not your cup of tea, the advice about positions, breathing, which muscles to use when, etc. is great.
