Not all in books. When you're studying under an obstetrician they will have their favorite texts and videos. But first you get your M.D. Then you do a training in obstetrics and gynecology. Congratulations on your goal. Assisting mothers to deliver their babies has been the favorite part of my general practice career. I took my wife to a remote island to meet a "baby" I delivered there 38 years ago. Very emotional.
