History of Family Planning

The desire, and the need to manage human fertility is part of the human experience. The methods can be moral or immoral. The motivation can be noble or base. These seemingly personal decisions have social ramifications that can help or harm society. This complex mix of factors can be seen in the history of family planning. Below are some resources that can shed light on this history.
