My copy of "First Ladies" is a 2nd edition from 1993, up to and including Hillary Clinton, early in Bill's first term. Other reviews indicate that newer editions are available and that there may have even been a format change. Having said that, my edition covers 49 women, which is a lot of information. Many of the mini-biographies were interesting but, by necessity, hit only the highlights. After awhile it became increasingly difficult to remember specific details about each of the women. Still, worth reading, particularly along with other sources to provide more depth (e.g. I went to youtube on several occasions to look at old footage of Eleanor Roosevelt, Bess Truman and others).
