A searching question inspired by Vipul Naik: Consider the period between 1930 and 1964.  What priority did libertarians give to the abolition of Jim Crow laws?  How many even considered the issue worth specifically addressing?

The first instances that come to mind are Rothbard’s 1961 “The Negro Revolution” in New Individualist Review and Ayn Rand’s 1963 “Racism”  in The Objectivist Newsletter.  What else have you got?  Please provide cites and URLs in the comments.
