For a project I'm researching Salk's polio vaccine and I've been searching everywhere for primary documents but only found material from the Eisenhower Presidential Library but I still need more primary resources because it's only reports that comes from the government. I prefer to obtain documents from Salk himself.
We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time. — T.S. Eliot
