I know what you mean about the books you want to read not being at the library. Frustrating when you have a limited budget.
I did buy Lynn Griesemer's book and was not all that impressed, although I know other people recommend it highly. I got a bit more out of Marilyn Moran's Pleasurable Husband/Wife Childbirth.
I found Jeannine Parvati Baker's Prenatal Yoga and Natural Childbirth inspiring in a way that suits my personality (though I have to admit I don't do yoga!) I also find Leilah McCracken's writing (birthlove.com) inspiring, though I have not read her book. I have sort of a love/hate relationship with Spiritual Midwifery; though I love the stories, I don't agree with some of the midwifery advice. Nontheless, it was one of the few books that I continued to read during the last few weeks of my pregnancy.
I would really recommend the video A Clear Road to Birth, too!
