There's a little section in Dr. Sear's "Pregnancy Book", maybe more detail in his book "The Birth Book", but I haven't read that one.
For a midwife's perspective on childbirth and lots of birth stories, Ina May's Guide to Childbirth is excellent.
Henci Goer's "The Thinking Woman's Guide to a Better Birth", I don't know if this is out of date now, I read it 5 years ago when pregnant with my first baby.
That's great that you are doing research and comparing, it helps to feel confident about your choices!
