I just read an article yesterday in this month's edition of Town & Country regarding the status of women as museum directors. If I remember my facts correctly, they reported that approximately 1/3 of the membership of the AAMD is female. The article also reported that most women directors are in small to medium sized museums, and that there are only a small number of women (like 2) who are directors of exceptionally large museums. It was interesting, but not very deep. It might be worth a look, but it was quite short.
