Getting started?

Hi,
I'm new to this group, and I usually read the message board at
midwifery.org.....
I'm very interested in becoming a midwife within the next few years.  I'm
currently studying to be a yoga instructor and my eventual goal in that is
to teach pre and post natal yoga.  I live in the Southern California area
but will be relocating within the next year to the San Francisco area.

I'm wondering if anyone could recommend books or areas of specific study
that I can follow on my own before starting midwifery training....any
websites, areas of study, schools, anything would be helpful.
Namaste
Jennifer
