Libertarianism: What Everyone Needs to Know - Jason Brennan Labels have become the bane of our political existence. If you don't want to read this book I highly recommend Brian Lamb's interview with the author which explains a great deal about the origins of Libertarianism (from the classic liberal) to what we now know as the "hard" libertarian.

I doubt if any of the explanation will make any difference given our propensity for assigning everyone to little niches and categories where they can be shunted aside, but it might help focus one's own thinking about where each of us falls on the political spectrum.
