"The Pill"

[W. Russell]

Hello;
        I am seeking a source, circa 1960's, America, that describes birth
control as part of a wider Feminist movement. This is an overly general
request, but I am looking for a quotation to use as a part of a painting I
am doing that interogates the state's use of sterilization as a form of
oppression in Canada. If anyone can suggest a source I would appreciate
it. 

Thankyou,
Wendy Russell
