The third edition of this book marks a time of

change and expansion in the profession. This

change and expansion is reflected in the title

and in the size of the book. The change in the title

fromNurse-MidwiferytoMidwiferyreflects the recent actions of the American College of NurseMidwives and the ACNM Certification Council,

which assumed responsibility for setting the standard for the practice of midwifery in the United

States through the credentialing mechanisms of accreditation and national certification of both nursemidwives and non-nurse-midwives.
